钢筋网水泥砂浆面层加固砖砌体结构振动台模型设计
|
摘要
试验设计的缩尺模型是以一栋八十年代典型三层砖砌体办公楼为原型,采用钢筋网水泥砂浆面层对其进行加固;探讨了该模型试验设计全过程的关键技术,包括墙体竖向压应力的模拟和钢丝网、水泥砂浆、砖砌体的材料协同工作等方面;给出了模型材料的选择、相似关系的确定、构造措施的做法、加固面层的做法、附加质量的确定以及仪器仪表的布置等;结合数值分析给出了在地震作用下该模型加固后的初步预测结果,为下一步通过地震模拟振动台试验验证该加固方法对砖砌体房屋整体加固的有效性做准备。
A scale model for shaking table test was designed in this article by taking a typical three-story-office building built in 1980s as the prototype.The model was strengthened with externally steel reinforced mesh mortar layer.The key techniques of the whole process of model test was discussed,especially the simulation of compressive stress in the cross section and the cooperation of the three different kinds of materials,i.e.reinforcement mesh,mortar layer and brick wall.Model material selection,the determination of similitude law,seismic design details,additional mass computation and the distribution of instrument are presented.Then the earthquake damages were predicted by numerical calculation,which is one preparation for the shaking table test.
