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.
