摘要

钢混组合梁兼具钢材的抗拉性能及混凝土的抗压性能,整体造价较钢梁有明显优势,在城市建设中具有明显的运用优势.然而,基于工程实例对钢混组合梁开展横向分布系数的研究和简化计算较为匮乏.因此,选取一项桥梁改造工程,以简支工字形钢混组合梁为对象,通过建立全桥梁格有限元模型分析桥宽、中间横梁间距、中间横梁强度、主梁片数等参数,研究简支工字形钢混组合梁横向分布系数.将其结果与刚性横梁法、刚接板梁法、比拟正交异性板梁法相比,简化了简支工字形钢混组合梁有限元计算.

Abstract

Steel-concrete composite beams have the tensile properties of steel and the compressive properties of concrete.At the same time,the overall cost has significant advantages compared to steel beams,which has obvious application advantages in urban construction.However,the research on the transverse distribution coefficient and simplified calculation of steel-concrete composite beams based on engi-neering examples is scarce.Therefore,a bridge reconstruction project is selected in this paper,and the object is simply supported Ⅰ-shaped steel-concrete composite beam.The transverse distribution coefficient of the simply-supported Ⅰ-concrete composite beams is studied by analyzing the parameters of bridge width,interbeam spacing,interbeam strength and the number of main beams.Compared with the rigid beam method,the rigid plate beam method and the orthotropic plate beam method,the finite element calculation of the simple supported Ⅰ-shaped steel-concrete composite beam is simplified.
