一种多功能拟静力试验装置

A Multifunction Pseudo-static Test Device

结构抗震的试验研究是结构抗震理论的重要组成部分。如何更加真实地模拟结构构件的压、弯、剪等多种受力性能以及解决试验加载方式和试验装置的不足等问题,一直困扰着广大土木工作者。为了提高实验室的科研教学能力和实验室使用效益,课题组自行设计、加工制作了一种多功能拟静力试验装置,该试验加载装置及设备主要采用反力墙、大型门架构架,液压伺服加载控制系统及竖向加载系统。通过科学、合理的设计,使得该装置不仅可以完成压弯剪型试验,还可完成剪切型破坏形式的大型试验。同时,该装置安装简单,灵活性强,占用实验场地少,节省空间。其中,装置的竖向加载系统由自行设计、制作的竖向稳压系统和水平滚动装置组成。相比其他传统竖向加载装置,利用杠杆放大及等压原理设计制作的杠杆放大式稳压装置,更好地解决了结构构件试验竖向稳定加载问题。利用这种多功能拟静力试验装置,已完成多项压弯型及剪切型大型抗震试验项目,试验效果理想、数据可靠,解决了部分试验能力不足问题,节约了大量资金。

The experiment research of structural seismic resistance is an important part of the structural seismic theory. How to realby simulate the structural component of the pressure, bending, cutting and mechanical properties of test methods and the problems of the test device, has been plagued by the civil workers. The members of the subject designed and made a multi-function shear test device. Through the scientific and reasonable design, make this device can not only complete hydraulic shear type seismic tests, but also can complete the form of seismic shear damage large trial. At the same time, this device installation is simple and flexible, not occupy experimental site and save a space. Among them, the vertical loading system is consisted of the vertical pressure system and horizontal scroll device which designed and produced by the subject. Compared with other traditional vertical loading devices, the stabilized device which uses lever amplifier and pressure principle solved the stability of vertical loading better. A number of bending and shear type earthquake tests had been completed by using the multi-function shear type test device. When it obtained the ideal and accurate results, it also solved the problems of the insufficieme of the experimental and save the money.
