Calculation of axial force by eccentricity of axial force

1.

The axial force of AC section is - 20KN, not - 10kN. Because - 10kN acts on point C, the AC is disconnected, the left part is taken as the isolator, and only the left end bears the axial force of - 20KN, so the axial force is - 20KN. Similarly, the axial force of CD segment is - 10kN, and that of de segment is + 10kN

For columns with large slenderness ratio, the initial eccentricity caused by various accidental factors cannot be ignored. With the increase of the load, the lateral deflection also increases. The compression deformation and bending deformation of the member occur at the same time. Finally, the member is destroyed under the combined action of axial pressure and additional bending moment

firstly, the concavity compressive concrete is crushed, the longitudinal reinforcement is bent and bulged out, and the concrete cover is peeled off; At the same time, when the convex surface is under tension, the concrete will proce horizontal cracks, the lateral deflection will increase sharply, and the column will be damaged

Extended data:

for short columns with longitudinal bars and stirrups, the strain of the whole section is basically uniform under axial load. When the load is small, the concrete and steel are in the elastic stage. As the load continues to increase, the lateral deformation of the concrete increases, the fiber stress at the edge of the section first reaches the tensile strength of the concrete, and micro cracks begin to appear in the column

After

because the elastic molus of steel bar is greater than that of concrete, the stress of steel bar increases rapidly, the stress of column longitudinal bar first reaches the tensile strength of steel bar and is crushed, and micro cracks begin to appear in the column

4 Battery capacity

Galaxy s10e: 3100mah (typical value)

Galaxy S10: 3400 MAH (typical value)

Galaxy S10 +: 4100 MAH (typical value)

typical value refers to the approximate average value obtained by weighted evaluation of deviation value after testing battery samples according to IEC61960 standard, The rated capacity corresponding to the above typical values is 3000 (Galaxy s10e) / 3300 (Galaxy S10) / 4000 (Galaxy S10 +) MAH. The actual battery life may change based on the specific network environment, use mode and other factors

5, memory

Galaxy S10: 8GB running memory + 128GB / 512gb storage space, Support microSD memory card (up to 512gb)

Galaxy S10 +: 8GB running memory + 128GB / 512gb storage space, 12gb running memory + 1TB storage space, support microSD memory card (up to 512gb)

SIM card slot 2 can be used as memory card slot, but SIM card and memory card cannot be inserted at the same time

4. Samsung S10 adopts a 6.1-inch new infinity-o curved surface hole digging screen design. The screen material is upgraded from the original super AMOLED to dynamic AMOLED. It supports hdr10 + and anti Blu ray function, and the screen display effect is further improved

How about Samsung S10

in terms of performance configuration, Samsung S10 adopts the latest generation of Qualcomm snapdragon 855 processor, new kryo485 architecture + 7Nm process technology + 2.84ghz main frequency capability, which makes Samsung S10 have a leap in computing processing capability compared with the previous generation. Specifically, compared with snapdragon 845, snapdragon 855 improves CPU performance by 29%, GPU performance by 37%, and energy efficiency by 40%. At the same time, Samsung S10 provides two storage configurations: 8g ram + 128G ROM and 8g ram + 512g ROM<

How about the Samsung S10

the Samsung S10 was upgraded from the previous generation of rear Dual Camera + front single camera to rear three camera + front single camera. Samsung S10 rear camera includes a 1600W ultra wide angle camera (F / 2.2), a 1200W intelligent variable aperture wide angle camera (F / 1.5 ~ F / 2.4) and a 1200W telephoto camera (F / 2.4). With the addition of ultra wide angle and the extension of variable aperture, Samsung S10 will be more outstanding in its excellent photography, especially in night scene shooting and wide angle shooting

How about the Samsung S10

in terms of front camera, the Samsung S10 adopts 1000W camera (F / 1.9) and supports full pixel al core focusing

in terms of other configurations, Samsung S10 is equipped with the latest under screen fingerprint identification sensor of Qualcomm, which is more sensitive than optical identification. In terms of battery capacity, Samsung S10 is equipped with 3400mah battery, which is 400mah more than the previous generation. The Samsung S10 supports wireless fast power and wireless shared charging function, and still retains IP68 level of st and water resistance

How about the Samsung S10

in terms of price, the US version of Samsung S10 starts at US $899, while the Bank of China Version is expected to start at RMB 6300.

Internet Protocol version 9 (English: Internet Protocol version 9, IPv9), also known as the ninth version of Internet communication protocol

IPv9 protocol refers to 0-9 Arabic numeral network as virtual IP address, and decimal system as text representation, which is a convenient way to find users on the Internet; In order to improve efficiency and facilitate end users, some of the addresses can be directly used as domain names

At the same time, it is also called "new generation safe and reliable information integrated network protocol" because it adopts the classification and coding of the business of the original computer network, cable radio and television network and telecommunication network

extended data

Internet Protocol version 4 (English: Internet Protocol version 4, IPv4), also known as Internet communication protocol version 4, is the fourth revised version in the development process of internet protocol and the first widely deployed version of this agreement

IPv4 is the core of the Internet and the most widely used version of internet protocol. Its subsequent version is IPv6. Until 2011, when the address of IANA IPv4 is completely exhausted, IPv6 is still in the initial stage of deployment

IPv4 is described in RFC 791 issued by IETF in September 1981, which replaces RFC 760 issued in January 1980

IPv4 is a connectionless protocol that operates on the link layer (such as Ethernet) using packet switching. This protocol will do its best to deliver packets, which means that it does not guarantee that any packets will arrive at the destination, nor does it guarantee that all packets will arrive in the correct order without repetition. These aspects are handled by upper layer transport protocols (such as transmission control protocol)
