中文摘要:

在这份报纸,钢水泥多精力驱散合成砍墙,增强钢的水泥(SRC ) 包括了柱,钢板(SP ) 深微笑,具体的墙和精力驱散脱衣,被建议。以便在地震以后学习多精力驱散行为和 restorability,低周期的装载测试的二个阶段在十个测试标本上被执行。在第一个阶段,有 SP 深横梁的不同数字的五个标本上的测试被执行,并且测试持续了直到排水量飘移到达了 2% 。在第二个阶段,薄 SP 被焊接到在第一个阶段测试的五个标本的双方,并且一样的测试在修理标本(指明的同样新的标本) 上被执行。忍受负担的能力,僵硬,韧性, hysteretic 行为和失败特征被分析因为阶段和结果此处被讨论。从这些结果,力量计算模型和公式外推此处被建议,用 ABAQUS 的模拟执行了;他们与测试结果显示出好同意。学习证明 SRC 列, SP 深横梁,具体的墙和精力驱散脱衣合作很好并且在精力驱散起一个重要作用。另外,这研究证明 shear 墙在地震以后有好可恢复性,并且焊接薄 SP 修理一面使变形的墙是一种适用的技术。

英文摘要:

In this paper, a steel-concrete multi-energy dissipation composite shear wall, comprised of steel-reinforced concrete (SRC) columns, steel plate (SP) deep beams, a concrete wall and energy dissipation strips, is proposed. In order to study the multi-energy dissipation behavior and restorability after an earthquake, two stages of low cyclic loading tests were carded out on ten test specimens. In the first stage, test on five specimens with different number of SP deep beams was carried out, and the test lasted until the displacement drift reached 2%. In the second stage, thin SPs were welded to both sides of the five specimens tested in the first stage, and the same test was carried out on the repaired specimens (designated as new specimens). The load-bearing capacity, stiffness, ductility, hysteretic behavior and failure characteristics were analyzed for both stages and the results are discussed herein. Extrapolating from these results, strength calculation models and formulas are proposed herein and simulations using ABAQUS carried out, they show good agreement with the test results. The study demonstrates that SRC columns, SP deep beams, concrete wall and energy dissipation strips cooperate well and play an important role in energy dissipation. In addition, this study shows that the shear wall has good recoverability after an earthquake, and that the welding of thin SP's to repair a deformed wall is a practicable technique.
