中文摘要:

一合成砍墙概念深基于水泥充满了钢试管(CFST ) 柱和钢板(SP ) 横梁在这被求婚并且检验学习。新墙由三个不同精力驱散元素组成:CFST 列;SP 深横梁;并且增强了水泥(RC ) 脱衣。RC 脱衣被打算允许核心结构的元素作为一个单身者工作的深横梁组织消费精力的 CFST 列和 SP。不同配置的六个标本在周期的装载下面被测试。产生数据此处被分析。另外,压力的数字模拟和为每个标本的损坏过程被执行,并且模拟为 SP 横梁为地点和跨度高度比率变化的一个范围被完成。模拟与测试结果显示出好同意。核心结构展出强壮的列弱的横梁结构的一个可锻的让步机制特征, hysteretic 曲线是丰满的并且合成砍几地震防卫衬里的墙展览。有装入箱内的 CFST 列和 SP 的 shear 墙标本的变丑深横梁设计看起来接近全部 shear 墙的。为 SP 深横梁的配置建立最佳的设计参数对墙的最好的地震行为枢轴。新合成砍墙对在造结构的地震设计的使用因此合适。

英文摘要:

A composite shear wall concept based on concrete filled steel tube (CFST) columns and steel plate (SP) deep beams is proposed and examined in this study. The new wall is composed of three different energy dissipation elements: CFST columns; SP deep beams; and reinforced concrete (RC) strips. The RC strips are intended to allow the core structural elements - the CFST columns and SP deep beams - to work as a single structure to consume energy. Six specimens of different configurations were tested under cyclic loading. The resulting data are analyzed herein. In addition, numerical simulations of the stress and damage processes for each specimen were carried out, and simulations were completed for a range of location and span-height ratio variations for the SP beams. The simulations show good agreement with the test results. The core structure exhibits a ductile yielding mechanism characteristic of strong column-weak beam structures, hysteretic curves are plump and the composite shear wall exhibits several seismic defense lines. The deformation of the shear wall specimens with encased CFST column and SP deep beam design appears to be closer to that of entire shear walls. Establishing optimal design parameters for the configuration of SP deep beams is pivotal to the best seismic behavior of the wall. The new composite shear wall is therefore suitable for use in the seismic design of building structures.
