摘要
针对抗震能力不足或没有考虑抗震设防的广大农村低矮房屋,依据传统的钢筋混凝土圈梁构造柱技术,提出了用高性能水泥复合砂浆钢筋网薄层(HPFL)加固砖混房屋圈梁构造柱位置砌体,形成HPFL窄条带组合砖圈梁构造柱。本文通过HPFL窄条带组合砖圈梁构造柱的足尺寸模型振动台试验(其中一层荷载模型简称ZK1,二层荷载模型简称ZK2),来观测、分析HPFL窄条带组合砖圈梁构造柱结构的抗震能力。试验结果表明,HPFL窄条带组合砖圈梁构造柱的抗震效果明显,随着HPFL窄条带宽度增大(钢筋根数增大),抗震性能增加,并给出了具体设计建议。
In view of the lack of seismic capacity or not considering the seismic fortification of rural houses,on the basis of the traditional techniques of reinforced concrete ring beam and structural column,let the high performance ferrocement laminate(HPFL) strengthen brick masonry building where there are ring beam and constructional column,the HPFL narrow strip combined with brick ring beam and constructional column is made.In this paper,through HPFL narrow strip combined with brick ring beam and constructional column full-scale model shaking table test(one-story load model referred to as ZK1,two-story load model referred to as ZK2),to observe and analyze HPFL narrow strip combined with brick ring beam and constructional column structure seismic ability.The test results show that,for HPFL narrow strip combined brick of circle beam and structural column the seismic effect is obvious,with HPFL narrow strip width increase(increased amounts of reinforcing bar),the seismic performance increases.A specific design recommendation is offered.
