由长细比求稳定系数表

钢结构稳定系数查表方法如下所示：1,首先需要确定构件的所属类别。2,然后去计算出换算长细比，这是公式：(Axsqrt(fy/235))3,和表中第一纵列对照一下，找出计算值的十位数(或百位和十位)是多少，确定横列；再看个位数，确定纵列。表中0-9纵列的用处就是这样，避免了使用线性内插法带来的不便。第一列是代表十位及百位数字,第一行是代表各位数字。例如长细比如果是23,那就对应第三行，第四列的数即0.938附录A计算系数A.1轴心受压构件的稳定系数A.1.1轴心受压构件的稳定系数可根据钢材的牌号按下列表格查得。表A.1.1-1Q235钢轴心受压构件的稳定系数中A012345678901.0000,9970.9950.9920.9890.9870.9840.9810.9790.976100.9740.9710.9680.9660.9630.9600.9580.9550.9520.949200.9470.9440.9410.9380.9360.9330.9300,9270.9240.921300.9180.9150,9120.9090.9060.9030.8990,8960.8930.889400.8860.8820,8790.8750.8720.8680.8640.8610.8580.855500.8520.8490.8460.8430.8390.8360.8320,8290.8250.822600.8180.8140.8100.8060.8020.7970.7930.7890.7840.779700.7750.7700.7650.7600.7550.7500.7440.7390.7330.728800.7220.7160.7100.7040.6980.6920.6860.6800.6730,667900.6610.6540.6480.6410.6340.6260.5180.6110.6030.5951000.5880.58。0.5730.5660.5580.5510.5140.5370.5300.5231100.5160.5090.5020.4960.4890.4830.4760.4700.4640.4581200.4520.4460.4400.4340.4280.423•1170.4】20.4060.4011300.3960.3910.3860.3810.3760.37!0.3670.362*3570.3531403490.3440.3400.3360.3320,3280,324一0.3200.3160.312ISO0.3080.3050.3010.2980.2940.2910.2870.2840・2810.2771600.2740.2710.2680.2650.2620.2590.2560.2530.2510.2481700.2450.2430.2400.2370.2350.2320.2300.2270.2250.2231800.2200.2180.2160.2140.2110,2090.2070,2050.2030.201扩展资料：钢结构必须注意防护，特别是薄壁构件，因此，处于较强腐蚀性介质内的建筑物不宜采用钢结构。钢结构在涂油漆前应彻底除锈，油漆质量和涂层厚度均应符合相关规范要求。在设计中应避免使结构受潮、漏雨，构造上应尽量避免存在于检查、维
