摘要:
通过进行往复荷载作用下的T形钢骨、槽型钢骨、聚丙烯纤维、钢纤维增强的混凝土异形柱中节点试验研究,分析不同改善措施对混凝土异形柱中节点滞回性能影响。研究结果表明:在混凝土异形柱中节点核心区加入T形钢骨、槽型钢骨或掺入聚丙烯纤维、钢纤维均能使混凝土异形柱中节点的承载能力得到提高,使中节点的滞回特性得到改善。四种改善措施均能提高混凝土异形柱中节点受剪承载力,其中加入钢骨对提高混凝土异形柱节点的受剪承载力效果优于加入纤维的。
Abstract:
The specially shaped columns interior joint reinforced by T-shaped steel, groove-shaped steel, polypropylene fiber, steel fiber were tested with low cyclic loading. The effect on hysteretic behavior of interior joint reinforced by four measures was researched. It is shown that the hysteretic characteristic of specially shaped column interior joint reinforced by T-shaped steel, groove-shaped steel, polypropylene fiber or steel fiber was improved, the bearing capacity of reinforced interior joint was enhanced. The shear capacity of joint reinforced by T-shaped steel, groove-shaped steel, polypropylene fiber or steel fiber is higher than that of without reinforcement. The shear capacity of steel reinforced interior joint is higher than fiber reinforced.
