摘要
分析了框架倾覆力矩不同计算方法各自的缺陷,经研究推导提出了框架倾覆力矩计算的合理方法,记为统一解方法。该方法推广了抗规法的适用条件,回答了采用力学法计算时的合理取矩点问题。通过普通框架结构、带侧向弹性支座的框架结构以及具有一般意义上的建筑结构中部分框架结构的研究,给出了在结构各楼层处作用有规定地震水平力下,框架倾覆力矩统一解算法的具体表达:柱剪法和梁剪法。统一解法的提出对建筑结构体系的判断、框架-剪力墙结构二道防线的抗震设计等方面具有重大意义。
The defects of different calculation methods of frame′s overturning moment were analyzed, and a reasonable calculation method of frame′s overturning moment was put forward, which was recorded as a unified solution method. This method generalizes the applicable conditions of the method in the seismic design code and answers the problem of the reasonable moment point in the mechanical method. Through the study of common frame structure, frame structure with lateral elastic support and inner frame structure in building structure in general sense, the concrete expressions of unified solution method of frame′s overturning moment under the action of specified earthquake horizontal force at each floor of the structure were given: column shear method and beam shear method. The unified solution method is of great significance to the judgment of the building structural system and the seismic design of the second defence line of the frame shear wall structure.
