【提要】 介紹了近四十年來不同高度的各類結(jié)構(gòu)形式(框架結(jié)構(gòu)、框剪結(jié)構(gòu)、板柱結(jié)構(gòu)、板柱剪力墻結(jié)構(gòu))的房屋在地震中的表現(xiàn)(好的或壞的)，分析了其原因。指出了現(xiàn)行國家規(guī)范中對(duì)框架結(jié)構(gòu)、板柱剪力墻結(jié)構(gòu)最大適用高度的規(guī)定的不妥之處，并提出了修改建議。同時(shí)對(duì)規(guī)范中某些易被工程師忽略、誤解的規(guī)定進(jìn)行了強(qiáng)調(diào)和說明。
【關(guān)鍵詞】 框架結(jié)構(gòu) 框剪結(jié)構(gòu) 板柱剪力墻結(jié)構(gòu) 倒塌 損壞 延性框架 脆性破壞 沖切破壞
Some Thoughts about Existing Code—the Maximum Suitable Height of Concrete Structural Building/Cheng Maokun,Yu Donghui(Beijing Institute of Architectural Design,Beijing 100045, China)
Abstract:The performance of many kinds of structural system is introduced in earthquakes during the past 40 years, some good and some bad,and the reasons are analyzed.It is pointed out that the maximum suitable height of frame structure and flatplate shearwall structure is not proper on Chinese existing code.Then the suggestions and the modifications are given.
Some regulations that are capably overlooked or misunderstood by engineers on code are emphasized and explained.
Keywords:frame structure;frameshearwall structure;flatplate shearwall structure; failure;damage;ductile momentresistant frame;brittle damage;punching shear failure
