高性能水泥复合砂浆钢筋网薄层(HPFL)窄条带加固技术具有造价低廉、施工简易、工作可靠等诸多优点。介绍了HPFL窄条带抗震加固砌体结构的研究成果:HPFL窄条带能显著提高墙体的抗震抗剪承载力、抗侧刚度、耗能能力和延性,并减缓墙体刚度退化的速度。结合工程实例,给出了具体设计和施工方法。经计算,加固前部分墙肢抗震承载力不满足要求,加固后各楼层墙肢均满足抗震承载力要求。
High-performance cement composite mortar Reinforced web (HPFL) narrow strip reinforcement technology with low cost, easy construction, reliable and many other advantages. The research results of HPFL narrowband seismic strengthening masonry structure are introduced. The narrow HPFL strip can significantly improve the seismic and shear bearing capacity, lateral stiffness, energy dissipation capacity and ductility of the wall, and slow down the stiffness degradation of the wall. Combined with engineering examples, given the specific design and construction methods. It is calculated that the seismic capacity of partial wall-limbs before reinforcement does not meet the requirements, and the reinforced concrete wall-walls meet the requirements of anti-seismic capacity.
