Further Numerical Analysis on Composite Steel Concrete Structural Shear Walls with Steel Encased Profiles

摘要

Numerical analysis were made on composite steel concrete structural shear walls with steel encased profiles to understand the theoretical behavior of the element in order to compare the results with those revealed by the experimental model. Composite steel concrete structural shear walls with steel encased profiles are a good alternative for high rise buildings that require considerable large lateral load resistance and strong axial load capacity. The encasement of the steel shapes in concrete is applied primarily for the following purposes: flexural stiffening and strengthening of compression elements; fire protection; potentially easier repairs after moderate damage; economy with respect both to material and construction. Construction and composite construction as well, has an important role to play in delivering sustainable development because of its contribution to national economy, and the significant environmental and social impacts that buildings can have. Scarce information about nonlinear behavior of composite steel concrete structural shear walls with steel encased profiles is available. The purpose of this work is to present numerical analysis on specified elements with different height/length ratios, for predicting nonlinear behavior, stress distribution, crack distribution, structural stiffness at various loads, and load bearing capacity of the proposed element.
