高层建筑结构设计质量的探讨

Study on the quality of structure design of the high-rise building

建筑设计质量的优劣决定了建筑施工质量的优劣和建造成本的高低,对建筑工程起着决定性的作用。研究表明,相对于建筑产品的全生命周期,设计成本可以少到忽略不计,但对建造成本的影响却高达70%~80%。文章主要从结构设计的各个阶段出发,探究了影响结构设计质量的重要因素,并结合工程实例探讨了正确处理各关键因素的重要性。方案设计阶段涉及结构体系、结构布置、构件尺寸和特殊技术措施等因素,结构计算阶段涉及模型的选取和计算、参数设置和计算结果的合理性判断等因素,施工图设计阶段涉及结构计算书和施工图绘制等因素。

The quality and cost of building construction have been decided by the quality of building design which plays a crucial role in construction engineering. The results show that the design cost could be ignored when it comes to the whole life cycle of a construction product. However,70% ~ 80% of the construction cost is determined by the quality of design. This paper mainly introduced the major factors of structure design quality,and discussed the importance of correctly dealing with these key factors through an engineering project. The factors in scheme design phase include structure system,structure layout,the size of components and special technical measures. The factors in structure calculation phase involve the selection and calculation of structure model,the parameter setting and the judgment about the rationality of calculation results. The factors in construction drawing design phase refer to the calculation book and construction drawing plan.
