竖向配筋砖砌体抗震性能试验研究及有限元分析
|
摘要
针对内蒙古中西部地区村、镇民居窗间墙宽度很小的特点 ,本文提出在南纵墙的窗间墙采用竖向配筋砌体 ,并据此进行了配筋墙片和无筋墙片的对比试验 ,并对配筋砌体进行了有限元分析。试验与计算结果表明宽度较小的竖向配筋砌体的抗侧力及水平刚度显著提高 ,抗震性能得到改善
In connection with the characteristic of the wall between windows with very small width in these town and village rural houses located in the mid?western region of Inner Mongolia, vertical reinforced masonry is proposed for such wall between windows in this paper. On such basis, comparative tests on walls with and without reinforcement are carried out. Besides, finite element analysis is conducted for the reinforced masonry. Test and calculating results show that the lateral resisting behavior and horizontal stiffness of the vertical reinforced masonry of small width are increased significantly, and its earthquake resistant behavior is improved.
