EXPERIMENTAL INVESTIGATION OF UNBONDED PRESTRESSED CONCRETE SIMPLY-SUPPORTED SLAB SUBJECTED TO FIRE
-
摘要: 在实现ISO标准升温曲线升温的前提下，通过对无粘结预应力混凝土简支板火灾下试验行为的研究，总结了无粘结预应力混凝土板变形、预应力变化的一般规律，考察了预应力度和保护层两种因素。试验的结果为以后更进一步研究打下了基础Abstract: The behaviours of the unbonded prestressed concrete simply-supported slab are investigated under fire based on?the premise that the ISO time- temperature curve would achieve.From the test result, the general regularities of deformation?and the change of prestressed force are presented.Two important factors, prestressing level and thickness of cover, are?examined.The test results provide a basis for further research in the future.
