［摘要］分析了框架傾覆力矩不同計(jì)算方法各自的缺陷，經(jīng)研究推導(dǎo)提出了框架傾覆力矩計(jì)算的合理方法，記為統(tǒng)一解方法。該方法推廣了抗規(guī)法的適用條件，回答了采用力學(xué)法計(jì)算時(shí)的合理取矩點(diǎn)問題。通過普通框架結(jié)構(gòu)、帶側(cè)向彈性支座的框架結(jié)構(gòu)以及具有一般意義上的建筑結(jié)構(gòu)中部分框架結(jié)構(gòu)的研究，給出了在結(jié)構(gòu)各樓層處作用有規(guī)定地震水平力下，框架傾覆力矩統(tǒng)一解算法的具體表達(dá)：柱剪法和梁剪法。統(tǒng)一解法的提出對(duì)建筑結(jié)構(gòu)體系的判斷、框架-剪力墻結(jié)構(gòu)二道防線的抗震設(shè)計(jì)等方面具有重大意義。

Abstract: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.

Keywords:overturning moment; frame; frame structure; frame shear wall structure
