结构构件用钢量影响因素案例研究

Case study on influencing factors of steel consumption for structural components

选取地震烈度、结构高度和结构体系3个主要影响因素,研究其对于楼板、结构梁、框架柱、剪力墙共计4类结构构件用钢量的影响效果及其敏感程度。首先对研究方法和选用案例进行了具体说明。随后,对楼板用钢量及其影响因素进行了具体分析。同时,对结构梁、框架柱、剪力墙3类结构构件的用钢量及其影响因素进行了详细说明。最后,对结构整体用钢量及其影响因素进行了重点介绍。研究结果表明:通过分析各类结构构件用钢量及其影响因素,可以有效掌握结构设计造价控制方向和控制重点,有效提升结构设计经济合理化程度。

Three main influencing factors,i.e.seismic intensity,structural height and structural system,were selected to study the effect and sensitivity of these three factors on the steel consumption of four types of structural members:floor,structural beam,frame column and shear wall.Firstly,the research methods and selected cases were explained in detail.Subsequently,the amount of steel used in floor and its influencing factors were analyzed concretely.At the same time,the steel consumption and its influencing factors of structural beams,frame columns and shear walls were described in detail.Finally,the steel consumption of the whole structure and its influencing factors were emphatically introduced.The results show that by analyzing the amount of steel used in various structural components and its influencing factors,the direction and focus of structural design cost control can be effectively grasped,and the degree of economic rationalization of structural design can be effectively enhanced.
