| 中文摘要: |
| 首先对一榀单层单跨的无粘结预应力混凝土框架进行了常温下的加载破坏试验 ,然后通过模拟真实火灾环境 ,对四榀单层单跨的无粘结预应力混凝土框架进行了不同恒载、不同升温曲线、不同预应力度各工况的火灾试验 ,并进行了试验分析 ,从而为无粘结预应力混凝土框架的火灾反应分析提供了可靠的数据. |
| 英文摘要: |
| In this paper, one single story one span unbonded prestressed reinforced concrete frame was tested under service loading at normal temperature, fire tests of four identical frames with different elevated temperature curves, different loads and different degrees of pretension were presented. Based on the test phenomena and data, response of the structure to fire was analyzed, and the reliable data were offered to the fire response analysis of the structure. |
