摘要
用一般手算法选择钢压弯构件截面时,往往要经过多次尺寸调整才能通过强度、整体稳定、局部稳定、刚度几方面的验算。该计算过程既繁又慢,且不易得到最优截面。为改进这一计算过程,本文列出了用电算法验算焊接H形截面钢压弯构件的计算公式,用BASIC语言编写了相应的计算机程序。算例表明,用本文程序设计的构件可比手算法省钢10%左右。
When selecting the cross-sections of steel beam-columns by hand calculation method,it often requires more than once size regulations to pass the checking of computations of strength, integral stability, local stability and rigidity. n,herefore, the computation process is both complicated and slow,and often we can't get the optimum cross-sections. In order to improve the calculation process, this paper sets cot check formulas of computer calculation method for the welded steel beam-columns of H-shaped cross-sections and presents a corresponding computer program with BASIC language. Examples show that members designed by the computer program introduced in this paper save about 10% steel compared with those designed by hand calculation method.
