连续直线钢箱梁剪力滞效应研究

Experimental Study of Shear Lag Effect in Continual Linear of Steel Box Girder

制作了1个2跨连续直线钢箱梁模型,并对该连续直线钢箱梁模型进行了均布荷载和集中荷载试验.详细介绍了试验过程,测试了各控制截面的各种力学性能指标,并对试验梁加载全过程进行仿真分析,将理论值与实测值进行了对比.分析了集中荷载和均布荷载作用下箱梁各控制截面应变及剪力滞分布规律.

Making a cross of two span continuous steel box girders of linear model,linear model for steel box girder of uniform load and concentrated load test,it introduces in detail the whole process of the experiment,testing the control sections of various mechanical properties,and the test beam loading process simulation analysis,the theoretical values were compared with the measured values.Analysis of the concentrated load and uniform load of box beam under each control section strain and shear lag distribution was conducted.
