摘要
3个钢纤维高强砼与2个普通高强砼的中节点抗震试验结果表明,核心区采用钢纤维高强砼可以较大幅度提高抗裂和受剪能力,少配或甚至不配箍筋,取消梁筋的附加锚固措施.本文提出的抗裂和受剪能力的计算公式,其计算值与试验值较为符合.
The test of seismic resistant behavior for throe frame joints using SFHSRC and two frame joints using high strength reinforced concrete is presented. The results show that the shear strength in the core region with SFHSRC has risen greatly, the shear stirrup can be decreased or cancelled and so can the extra anchorage measures. The formulas of calculation for cracking and ultimate shear strength are proposed. The calculated values are in acordance with the test ones.
