在进行钢筋混凝土结构计算时,按我国设计规范(TJ10—74,以下简称规范)正文中的公式计算钢筋混凝土梁的挠度太繁。而用规范附录六验算梁截面最小高度的方法虽较简单,但仍不理想,一是验算后如不满足梁截面最小高度要求,仍需按正文中公式作挠度验算,此情况不但没有省事反而增加了验算梁截面最小高度的计算工作量,二是用规范附录的方法查图表不准确,且该法仅适用于在一般情况下可不作挠度计算,在特殊情况下仍需作挠度验算;用钢筋混凝土结构计算手册中查图表方法也较繁琐,且精度不高。为解决上述问题,笔者推导出了直接计算承受均布荷载或集中荷载钢筋混凝土单
When calculating the reinforced concrete structure, the deflection of the reinforced concrete beam calculated according to the formula in the text of the Chinese design specification (TJ 10-74, hereinafter referred to as the specification) is too many. The method of checking the minimum height of the beam section in Appendix 6 of the Rules is relatively simple, but it is still not ideal. First, if the minimum height requirement of the beam section is not satisfied after the calculation, the deflection in the main text shall still be used to check the calculation. This situation is not only not saving but Increased the calculation of the minimum height of the beam section calculation, and second, the use of the specification appendix to check the chart is inaccurate, and the law is only applicable to under normal circumstances can not be calculated deflection, under special circumstances still need to do deflection checking; The method of checking charts in the calculation manual of reinforced concrete structures is also cumbersome and the accuracy is not high. In order to solve the above problems, the author deduced directly to calculate the reinforced concrete that withstands uniform load or concentrated load.
