剪跨比对实腹型钢混凝土梁斜截面承载力的影响性分析

西安建筑科技大学自1985以来进行了一大批型钢混凝土梁试验(39个),通过试验研究了型钢混凝土梁的剪切受力机理、破坏形态、应力应变关系以及影响其抗剪强度的因素等,并结合国内外已有试验资料总结出一套关于型钢混凝土梁斜截面的计算分析理论。本文依据其已有理论通过Visual For-tran程序语言编译出来,利用所编程序分析实腹型钢混凝土梁的斜截面承载力Vu以及构成该斜截面承载力的混凝土抗剪能力部分Vc和型钢抗剪能力部分Va受剪跨比影响的变化规律、成因以及各组成部分的相同及差异性,旨在对已有理论深入和细化,并为后续实验提供参考研究。

Analysis for Shear Force of Solid-web Section Steel Reinforced Concrete Beams Influenced by Shear-span Ratio

Xi′an University of Architecture and Technology have conducted a quantity of experiments about section steel reinforced concrete beams(39 pieces) since 1985.Through these experiments,the shear stress mechanism,fracture morphology,the relationship of stress and strain as well as the influence elements on the shear strength of the beam are studied,and combined with the domestic and external testingdata,a series of computing and analysis theory is concluded.In this article,the program about the theory is writen by the programming language of Visual Fortran.By the program,the regular changes,factors,the sameness and otherness of components,the shear load-carrying capacity of section steel reinforced concrete beams,and the shear strength of shaped steel and concrete are analyzed,which are the important parts of shear load-carrying capacity influenced by shear-span ratio.The aim is to deepen and detail the theory and supply references for follow-up experiments.
