1.
Calculation of truss axial force with node method:
two unknown forces can be obtained from a node equation, generally starting from the support node and proceeding in turn. For a node, if the member is removed and replaced by force along the member direction, it can be assumed that it is tensile force (if the force is negative, it means pressure). The equilibrium equations in X and Y directions are listed respectively (the forces are projected into the equilibrium equations in X and Y directions respectively): ∑ x = 0 ∑ y = 0. The specific form may be as follows: f1cosa + f2cosb + acosc = 0, f1sina + f2sinb + asinc = 0, where a represents the known force, F1 F2 is the unknown force. The unknown forces F1 and F2 can be obtained by solving the equations. The positive value is the tensile force and the negative value is the pressure
2. It's very simple. Analyze the force at point B, and calculate the sum of longitudinal force and transverse force as 0.
3. According to the building height, the section size of beam and column, the thickness of floor and roof panel, wall material and thickness, decoration method and roof live load of factory building, the axial force of center column, side column and corner column is calculated or roughly calculated in combination with the code for design of building structure and code for seismic design of buildings. In fact, it's very fast to calculate with software
when estimating the area of foundation bottom, the factor of foundation buried depth should also be considered
for reference only. I wish you all the best.

4. I don't know what to do with my daughter. Of course, I have to find a third party to manage it.
5. Most hospitals in Beijing have launched special outpatient service, which means that the registration fee is more expensive, and most of them can see a doctor on the same day
6. It's on the top of the mountain right below lockmodan
7. Hanzhong central hospital works on Saturdays and Sundays, but there are only doctors on ty in some departments. Finally, I wish you all the best!
8. Some events in the field of ecation can easily become the focus of public opinion. However, people tend to pay attention to "what happened" in the field of ecation, but pay little attention to "what didn't happen" in the field of ecation
some events in the field of ecation can easily become the focus of public opinion. However, people tend to pay attention to "what happened" in the field of ecation, but pay little attention to "what didn't happen" in the field of ecation
many teachers and people of insight know that in recent years, in the face of students' violations, fewer and fewer teachers dare to severely criticize and moderately punish them
teachers' right of punishment, as a natural right of ecators, is quietly losing. People are unaware of this, but have to bear the consequences: in the face of illegal students, teachers dare not, can not, do not want to manage
the loss of the right of punishment leads to the distortion of the relationship between teachers and students, the lack of effective prevention of campus bullying, and the frequent occurrence of students beating teachers....
"teachers are the engineers of human soul" and "teachers are the most glorious profession under the sun"... These famous sayings have made countless teachers proud. But times seem to have changed. When the ruler is not on the platform and the whip is not in hand, when the administrative department of ecation repeatedly admonishes that we should be cautious, and when we hold back again and again, "forget it, one more thing is better than one less thing", the teachers who have lost the right of punishment sigh: in the face of students, we only teach knowledge, not teach people
no strict control means no love. Is it only teachers who lose the right of ecation punishment
dare not manage, can not manage, do not want to manage
"punish students, we are afraid of"
punishment station dare not punish for a long time, criticism dare not say heavy, as long as the parents come to make trouble, the school is mostly in a weak position, and then the teacher is asked to write review, dection salary. This is the general reflection of dozens of primary and secondary school teachers interviewed by the half moon reporter in Jiangsu, Shandong, Jiangxi and other places a few days ago
"in front of parents, the school still counsels." A primary school teacher in Jiangsu Province told reporters that a colleague asked the students who didn't do the homework because most of the students didn't do it. He asked them to stand at the back of the classroom for a class. Then the parents went to the school to make trouble. Finally, the colleague made a review at the school meeting
LUO Tiantian, a Chinese teacher at No.28 middle school in Nanchang City, said frankly: "if the teacher punishes the students to take professional risks, then I don't need to." Teachers choose to be wise, because in case of conflict between teachers and students, it must be teachers who are "wrong"
"in the 1980s, there was no problem with a ruler. There was a strong social atmosphere of respecting teachers and ecation, but now it can't. When disciplining students, teachers naturally seek a sense of security. " Fu Jian, a sixth grade Chinese teacher in Honggutan campus of Nanchang primary school attached to Nanjing Normal University, sighs
Wang Hui, the executive principal of Dieshan Road Campus of Nanchang primary school attached to Nanjing Normal University, who has been teaching for nearly 30 years, said that the relationship between teachers and students is no longer pure. Teachers take charge of students, keep alert and can't let go of their hands and feet. The last way is to invite parents
when interviewing a primary school in Nanchang, the reporter heard that a teacher slapped a student who disobeyed the rules and provoked the teacher. As a result, the parents, the Ecation Bureau and the school put all kinds of pressure on the teacher. Finally, the teacher apologized to the student in front of the whole class according to the parents' request
"if you are eager to do something, the follow-up will be very troublesome." In the interview, the teacher's colleagues said that it hurt the teachers' hearts
nowadays, there is a sense of "powerlessness" in the teaching community. Some teachers try their best to avoid embarrassment, let alone punishment, in order to keep their dignity as teachers<
"dare not punish" hurt who
just ring the reporter's interview, a primary school in Jiangxi Province had students punching, kicking and slapping teachers. The teacher used the method of "standing for a while" to punish the student who disturbed the classroom discipline. The student overreacted. Several teachers in the school expressed "cold heart" and "Sadness". In the face of the reporter's interview, school principals and teachers all hope to "calm down". Similar cases are not uncommon
teachers often don't know how to deal with students' misbehavior on campus or in the classroom. Many teachers sigh that the profession of teacher is no longer "engineer of human soul". "We can only teach knowledge now, we don't dare to teach people," said Huang Qian, a fourth grade Chinese teacher at Dieshan Road Campus, Affiliated Primary School of Nanjing Normal University
punishment is the need to maintain the normal order of ecation and teaching, and it is the right of every teacher. Teachers dare not, can't and don't want to manage. Teachers only teach, but only hurt teachers' dignity
born in the countryside, Fu Jian thinks that he was not a good student when he was a child, and teachers often beat and scold him, "but I am very grateful to the teachers. My sense of rules today is inseparable from the strict control of teachers in primary and secondary schools.". Fu Jian believes that a child is like a tree. In addition to sunshine, rain, temperature and soil, it needs pruning and pruning. Only in this way can a tree grow into a towering tree
no rules, no circles. The lack of sense of rules in the process of growing up is a common problem for children. Sun Wei, director of the Chinese teaching and research section of Jining No.1 Middle School in Shandong Province, said: "some things make teachers feel cold. So how do we protect ourselves? I don't care. It's the children who hurt in the end. " Zhang Yuequn, a teacher at the primary school attached to Nanshi Normal University, said: "the sense of rules is weak and there is no timely ecation. In the future, it is not the teacher who slaps the children, but the society."
nowadays, there are a lot of chaos such as "campus bullying". A healthy ecational environment requires the participation of multiple subjects and the joint implementation of ecational responsibilities. In order to achieve good governance effect, moral ecation should be put in the first place, and teachers' disciplinary power should play a warning role< Why don't teachers hold up the "ruler"?
Wang Hui told reporters that it can't be said that teachers don't have any disciplinary power, but they are "too weak". Weak to the teacher to become a high-risk instry, a vulnerable group
what weakens teachers' disciplinary power? Why do teachers now dare not raise the "ruler" and do not want to raise the "whip"
the only child family ecation lacks normal guidance. Fu Jian believes that now only child families are common, especially a group of only child families have become parents. Their self-centered consciousness formed in the original family continues to exist in the children of new-born families, believing that the children can not be harmed. In fact, most teachers' punishment is not a kind of injury, but out of love. Wang Hui believes that taking children too seriously and pampering them is very harmful to their growth. Some children are too pampered since childhood and have weak ability to resist pressure. Some take running away from home and jumping off buildings as a way to deal with their parents
happy ecation is deeply rooted in the hearts of the people, and the society is no longer tolerant of ecation punishment. In recent years, many people unconsciously no longer recognize that ecation punishment is a necessary means, it seems that learning should be happy, teachers can only be kind to students, as time goes by, some students lack awe of teachers. Yan Guoan, a physics teacher at No.28 middle school in Nanchang, said that some students do not pay attention to their teachers and have no awe of them. "I've been scolded by my students for being old and immortal."
it is difficult to reach a consensus among society, parents and schools. Hu Jianshe, a researcher of Ideological and moral ecation in Nanchang Institute of Ecational Sciences, appeals that parents should give some understanding and support to appropriate ecational punishment, and healthy teacher-student relationship needs to be established with joint efforts. Gao Hongyan, the principal of Shengfu Experimental Primary School in Jinan, believes that more consensus should be reached on ecational punishment, that is, ecational punishment is not an inhumane, anti ecational and backward way of ecation, but a part of modern ecation. Only the effective combination of society, family and school can ecate the next generation well.

Under normal circumstances, the hospital will divide the daily number of registration into two parts. One part is used for online registration to meet the needs of patients who can use network tools. The other part is used for hospital window registration, mainly for the convenience of those who can't use network tools. I don't know what hospital you are talking about. If it is a hospital with very tight resources, Under normal circumstances, the hospital window registration will have long been queuing up, it will be difficult to buy
I don't know whether the hospital will completely use network registration in the future. At present, there are still some windows for registration, but the amount is not too much, so we need to queue up in advance
