【摘要】 对2块现浇冷轧双翼变形钢筋混凝土双向板进行了荷载试验,研究了双向板在均布荷载作用下的受力性能。试验结果表明:现浇冷轧双翼变形钢筋混凝土双向板的承载力较高,当钢筋强度设计值取400N/mm2时,承载力检验系数仍可满足规范要求。在使用荷载作用下,双向板具有较好的工作性能。更多还原

【Abstract】 To investigate the mechanical behavior of cast-in-situ two-way concrete slabs reinforced by cold-rolled deformed bars with double-wing,the test of two cast-in-situ two-way concrete slabs subjected to vertical uniform loads is carried out.The test results show that the cast-in-situ two-way concrete slabs reinforced by cold-rolled deformed bars with double-wing have high load-bearing capacity and their load-bearing inspection coefficient can meet the requirement of the codes related,and that the mechanical behavior of the slabs is better at working loads when the design value of strength of bars is raised to 400Nmm~2.更多还原
