陶粒混凝土T形柱抗震性能试验研究

在试验的基础上,讨论了剪跨比、轴压比、暗柱、荷载角、肢高厚比以及配箍率对陶粒混凝土T形柱抗震性能(水平承载力、刚度、延性)的影响,比较分析了陶粒混凝土T形柱和普通混凝土T形柱抗震性能的异同。剪跨比小、轴压比低、设有暗柱或箍筋加密的T形陶粒混凝土柱抗震性能较好;普通混凝土T形柱的抗震性能好于陶粒混凝土T形柱的。

Experimental study of aseismic behavior on ceramsite concrete T-shaped columns

Based on the experiment,the influence of shear-span ratio,axial pressure ratio,concealed column,loading angles,ratio of highness and width of section and stirrup ratio on aseismic behavior(horizontal bearing capacity,stiffness and ductility) of ceramsite concrete T-shaped columns are dicussed.Aseismic behavior of ceramsite concrete T-shaped columns and common concrete T-shaped columns are compared and analyzed.Finally,it's concluded that low shear-span ratio and low axial pressure and with concealed column or dence stirrup ceramsite concrete T-shaped columns are excelled in aseismic behavior,aseismic behavior of common concrete T-shaped columns is better than ceramsite concrete T-shaped columns.
