The structural behavior of these bridges, however, is complex and requires careful analysis. One of the key factors affecting the dynamic behavior of the cable-stayed bridge is the shear hysteresis effect that occurs in the concrete box beams.Shear hysteresis effect is a phenomenon in which the stiffness of the structure changes due to cyclic loading. This effect has a significant impact on the seismic performance and long-term durability of the cable-stayed bridge. Therefore, it is crucial to quantify and analyze the shear hysteresis effect in order to improve the design and engineering of these structures.Objective:The objective of this study is to analyze the shear hysteresis effect of concrete box beams in cable-stayed bridge with single inclined cable plane under dynamic loading. Specifically, the following tasks will be carried out:1. Develop a theoretical model for the dynamic analysis of the cable-stayed bridge with single inclined cable plane.2. Investigate the shear hysteresis effect in the concrete box beams using finite element analysis.3. Validate the finite element analysis results with experimental data.4. Quantify the impact of the shear hysteresis effect on the structural response of the cable-stayed bridge.Methodology:The methodology for this study will involve a combination of theoretical analysis, finite element modeling, and experimental testing. The theoretical analysis will be based on existing literature on cable-stayed bridges with single inclined cable plane. The finite element modeling will be performed using software such as ANSYS or SAP2000. The experimental testing will involve conducting dynamic tests on a physical model of the cable-stayed bridge.Expected Results:The expected results of this study are:精品文档---下载后可任意编辑1.
