問：薄壁（bì）焊（hàn）管（guǎn），鍍鋅薄壁焊管（guǎn）的豎向繼續力怎樣進行計算呢？上述進行計算都（dōu）是更為簡便的進行計算，與此同時同時全麵考慮更為（wéi）安全（quán）膨（péng）脹係數，甚至還會地振動載重，混凝土的狀況進行分析請有（yǒu）實際經驗的更為專（zhuān）業（yè）工程師進行計算，上述材料僅供進行商量采用。
Question: How to calculate the vertical bearing capacity of thin-walled welded pipe and galvanized thin-walled welded pipe? The above calculation is simple, and safety factor, even seismic load, should be taken into account. Experienced professional engineers are required to calculate the specific situation. The above information is for reference only.
答： 1.進行計算壓剪應力（lì），就是說豎向壓強實際作用在（zài）薄壁焊管的（de）橫進行部分上所形成的壓剪應力。就是說壓強（機構N）同時除以薄壁焊管橫進（jìn）行部分表麵積（機構m正方形）。隻需（xū）壓剪應力低於材料的許（xǔ）用剪應力（lì）相對即可。
Answer: 1. Computational stress is the compressive stress produced by vertical pressure acting on the cross section of thin-walled welded pipe. It is the pressure (unit N) divided by the cross-sectional area (unit m square) of the thin-walled welded pipe. As long as the compressive stress is less than the allowable stress of the material. 2.薄壁焊管持續受壓，要進行計算保持穩定性。保持穩定性的進行計算較比較為複雜。要看包括的方法是雙方固接如果一方麵固接另一方（fāng）麵持續鉸接。預計你不隻采用1跟立柱，因此能夠更為簡便（biàn）進行計算成雙方（fāng）固接。卡脖子壓強更為簡（jiǎn）便進行計（jì）算：P=(4*n*Pi^2*E*I)/[(L/2)^2]。n立柱（zhù）的數額，pi^2就是（shì）說拍的2次（cì）方，E柔性模（mó）量，I惰性矩，L立柱（zhù）長度。
2. The stability of thin-walled welded pipe under pressure should be calculated. The calculation of stability is complicated. It depends on whether the connection is fixed at both ends or hinged at the other end. It's estimated that you don't only use one post, so you can simply calculate it as a two-end fixture. Simple calculation of critical pressure: P=(4*n*Pi^2*E*I)/[(L/2)^2]. The number of n columns, PI ^ 2 is the second power of beat, E modulus of elasticity, I moment of inertia, L column length.
參（cān）加（jiā）5月度後，地方麵是現貨市場領域去存（cún）貨化保持連續（xù）進（jìn）行，除此之（zhī）外地方麵是中上遊薄（báo）壁焊管廠（chǎng）保持連續進行的（de）上位粗鋼（gāng）日產（chǎn）量造成外部存貨更加較大，在調職出廠價的鬼點子下，比較（jiào）而言過去的（de）廉（lián）價薄壁焊管可用資源目前已（yǐ）經交叉發往現（xiàn）貨鋼（gāng）市，預測最近一段時間或許進行齊集到市，也許將對薄壁焊管廠隻不過（guò）提出的使原有水平得到提（tí）高鋼價形成鉗製。
After entering May, on the one hand, the de-stocking of the spot market continues, on the other hand, the continuous high crude steel output of the upstream thin-walled welded pipe factory leads to a large internal stock. Under the means of lowering the ex-factory price, the low-cost thin-walled welded pipe resources have been sent to the spot steel market one after another. It is expected that they may be concentrated in the market in the near future, and perhaps the steel price just raised by the thin-walled welded pipe factory will be raised. Constraints arise.
