【摘要】 本文讨论了Neal & Symonds求框架破坏机构的原则,提出了一种计算机程序,可以从大量可能的组合机构中求得真正的破坏机构,从而很快地确定极限荷载。本文所提方法不仅使Neal & Symonds原则得到实际应用途径,而且节省了大量繁琐的计算过程。文中首先用手算例题对此法加以分析说明,随之用编制的计算机程序RFMC自动地进行机构组合并求得极限荷载。文中还通过解算两层框架的极限荷载,说明此法同样可应用于分析多层框架。更多还原

【Abstract】 The principle of Neal and Symonds to find the possible mode of collapse mechanism is discussed in this paper". A computer program RFMC is suggested which is able to get the real collapse mechanism of a framed structure from a lot of possible combined mechanisms and find the value of the ultimate load. This method not only helps the principle of Ncal and Symonds to find wide application but also avoids the tedious numerical calculation.This paper gives a numerical calculated example to illustrate how to use the suggested method and at the same time gives the procedure of using computer program RFMC to obtain the ultimate load by combining automatically the possible collapse mechanisms.From the example of finding the ultimate load acting on a two-storey framed structure, it can be concluded that this method is applicable to multi-storey frames as well.更多还原
