【摘要】 主要研究了受火无粘结预应力混凝土简支板的温度场分布和板的变形情况 ,并给出了钢筋保护层的厚度、预应力度对无粘结预应力混凝土简支板受火性能的影响。为无粘结预应力混凝土板的火灾行为的理论研究提供了依据。更多还原

【Abstract】 The behavior of simple supported slabs of unbonded prestressed concrete under fire is investigated. From the test results, the regularities of temperature field and deformation are presented, and the effect of different concrete covers and prestressing level on the behavior of the slabs is given. Results provide a basis for further research to explore fire behavior of prestressed concrete structures with unbonded tendon.更多还原
