【摘要】 虽然我国抗震规范中指出“宜进行多道抗震设防”,但并无具体、明确的条文规定。针对配筋砌体结构,提出了把抗侧力构件分成主抗侧力体系和次抗侧力体系两部分的思想,认为抗震设计过程中应实现对主抗侧力体系的保护,才能是安全可靠的抗震设计;结合配筋砌体构件骨架曲线的特点,给出了具体的设计步骤和设计实例及相关的补充说明;算例分析表明了本文方法的必要性、有效性和可行性。更多还原

【Abstract】 Although the Code for Aseismic Design of Buildings stipulates that ?(the structures) should be designed with multi-aseismic resisting systems? no specific items are given. In this paper, aimed at the aseismic design of reinforced masonry structures, the authors present a method to divide all the walls into two groups: the primary and the secondary lateral load resisting system. It is argued that only when sufficient care is taken during the design procedure of the primary system, the structure can be safe to survive earthquakes. Using the characteristic of the skeleton curve of the reinforced masonry wall, the authors present a full set of design steps. An example and some supplement explanations are also given. It is shown that the present method is valid and practicable.更多还原
