| 中文摘要: |
| 在试验的基础上,对建筑中常用的Q235钢在火灾条件下的力学性能进行了研究,获得了Q235钢的屈服强度、极限强度、弹性模量、极限应变等力学性能随温度变化而变化的规律,并对影响Q235钢力学性能的因素进行了分析。 |
| 英文摘要: |
| The mechanical performances such as yielding strength, limiting strength, elastic mould and limiting stain were studied under fire condition for Q235 steel which is commonly used in construction. The mechanical performances generally vary with temperature. The influencing factors of the mechanical performance were analyzed. |
