带有施工缝钢筋混凝土框架柱抗震性能试验研究 带有施工缝钢筋混凝土框架柱抗震性能试验研究 河北工业大学硕士学位论文 河北工业大学硕士学位论文 PAGE PAGE iv EXPERIMENTIAL STUDY ON SEISMIC PERFORMANCE OF REINFORCED CONCRETE FRAME COLUMN WITH CONSTRUCTION JOINTS ABSTRACT In recent years ,earthquake disasters Frequently occurred , earthquake resistant capability of residential buildings have been paid more and more attention . Through the Post-seismic Damage Assessment of the buildings in disaster area , we found that a large number of collapse of frame structure buildings have common phenomenon that the damage of construction joints of frame column capitals is more prominent . In the actual construction many construction units do construct unstrictly according to the construction standard of treatment method of construction joint , the influence of the way to the frame column of seismic performance need experimental study . This paper introducts the test of 9 test columns under low cyclic static loading ，Study the effect of seismic performance on the frame column ends of different axial compression ratio and processing methods of construction joint surface . Described the damage of the test columns，and based on the obtained data，gain specimens of seismic performance index ，such as hysteretic curve, steel strain curve, skeleton curve, displacement ductility, and strength degradation 。Through compare and analysis of different test conditions ，the result draw the colusion that HYPERLINK /translate?query=Axial%20compression%20ratio%20under%20certain%20conditions%20affect%20a%20construction%20joint axial compression ratio under certain conditions can affect the seimic performance of frame columns with construction joint . In the low and middle Axial compression ratio the seismic performance of specimen is reduced and should construct strictly according to the construction standard of treatment method of construction joint . In the high axial compression ratio the influence of construction joint and its processing method for the seismic p
