不同类型异形柱耐震性与适用性分析
|
摘要
目前对普通钢筋混凝土异形柱、带暗柱钢筋混凝土异形柱、型钢混凝土异形柱的适用性研究较少。研究采用延性系数、承载力、耗能能力及极限侧移角反映异形柱的耐震性,采用含钢率反映异形柱的经济性。在此基础上,可分别用延性系数、承载力、耗能能力、极限侧移角与含钢率的比值确定不同类型异形柱的适用性。研究结果表明:当含钢率在3.00%~4.00%时,普通钢筋混凝土异形柱的适用性较好;当含钢率在1.66%~3.00%或者4.00%~8.00%时,带暗柱钢筋混凝土异形柱的适用性较好;当含钢率大于8.00%时,采用型钢混凝土异形柱。研究成果可为工程实践提供参考。
At present,a few studies are made about the specialshaped columns of normal reinforced concrete,concealed-column reinforced concrete and steel reinforced concrete.The seismic resistance of special-shaped column can be presented by ductility coefficient,bearing capacity,capacity of energy dissipation and limited sideway displacement,and the economic capacity of special-shaped column can be presented by steel ratio.Based on these,the applicability of different kinds of special-shaped columns can be decided by the ratio of ductility coefficient and steel ratio,bearing capacity and steel ratio,capacity of energy dissipation and steel ratio,and limited sideway displacement and steel ratio respectively.The study and analysis results show that when the rang of steel ratio is between 3.00%～4.00%,the applicability of the special-shaped column of normal reinforced concrete is much better;when the rang of steel ratio is between 1.66%～3.00% or between 4.00%～8.00%,the applicability of the special-shaped column of concealed-column reinforced concrete is much better;and when the steel ratio is over 8.00%,the special-shaped column of steel reinforced concrete can only be used.The researched results can be used for the references of engineering practice.
