摘要
文中对混凝土短柱抗震性能承载力进行了试验研究,设计了两组试件进行比较,试件一是低温状态下的混凝土试件,试件二是常温状态下的混凝土试件。分析了低温下混凝土短柱的抗震性能,包括开裂荷载和极限承载力。试验表明,混凝土短柱在低温状态下,开裂荷载和极限承载力都有所下降。
In this paper, the experimental research was inforeed concrete short column, two groups of specimens was conducted on the seismic performance of redesigned to compare, a group is the normal temperature of reinforced concrete specimen, the other is a set of reinforced concrete specimens in low temperature. The low temperature effect on the seismic performance of reinforced concrete short columns is analyzed, including cracking load and ultimate bearing the cracking load and ultimate bearing capacity of the capacity. The test show that in low temperature concrete short columns has a significant decline.
