关于框架结构破坏机制的探讨

Discussion on how to achieve an idealization in the design about destructive mechanism of framework structure

框架结构是一种常见的结构形式 ,了解其破坏机理就能针对体系的薄弱环节 ,采取措施予以加强 ,以提高结构的抗震性能。在工程设计中应尽量避免结构产生楼层破坏机制 ,且在框架计算中将梁的固端弯矩进行适当调幅是达到理想破坏机制的手段之一。

The framework structure is a common structure form, knowing its destructive mechanism. We can take measures to strengthen it aiming at the weak link for improving the earthquake resistance of the structure. In the project design, the floor destructive mechanism arose by the structure should be avoided.In the framework calculation, it is one of the ideal methods of destructive mechanism to appropriately modulate the amplitude of the bending moment in the fixed end restraint of the beam.
