摘要
高强钢筋的应用可减少钢筋用量,降低工程造价。为了研究配置高强钢筋混凝土框架的抗震性能,运用有限元软件Open Sees对HRB335、HRBF400、HRBF500级钢筋混凝土框架在7度多遇、设防及罕遇地震下的抗震性能进行了数值模拟和详细的参数分析。采用框架梁、柱端塑性铰区的变形状态来标记损伤破坏程度。结果表明,随着地震作用的增大钢筋混凝土框架最大顶点位移、残余变形和梁、柱节点损伤逐渐增大。相同等级地震作用下的最大顶点位移基本相等,而震后残余变形随着钢筋强度等级的提高而减小,框架梁、柱节点损伤的程度逐渐降低。高强度等级钢筋的应用可减小框架的损伤,提高框架的抗震性能。
By use of high strength steel bars,steel quantity and project cost could be decreased. In order to investigate the seismic behaviors of concrete frames reinforced with high strength steel bars,finite element software Open Sees was used to numerically simulate the seismic behaviors of RC frames of grades HRB335,HRBF400,HRBF500 under Intensity 7 frequently occurred,fortification and seldom occurred earthquakes and conduct detailed parameter analyses The deformation state of the plastic hinge region at frame beam-column end was used to mark the degree of damage and failure. The results show that with the increase of earthquake artion,the maximum vertex displacement,residual deformation and beam- column joint damage of reinforced concrete frames increases gradually.Under the same intensity earthquake,the maximum vertex displacement is equal basically,but the residual deformation and the damage extent of frams' beam-column joints reduce with the increase of steel bars' strength. The application of high- strength grade steel bar could reduce the damage of frames and improve the seismic performance of the frames.
