STUDY ON THE SEISMIC RESISTANCE OF MULTI-SPAN FRAMES WITH MULTI-STORY COLUMNS SUBJECTED TO VARYING HIGH AXIAL LOADS
|
�´˜^�i‰p�j�F
One of the most important problems in structural design of high-rise RC buildings is the change of high axial forces acting on the external columns during earthquakes. It has been stated in numerous experimental studies that a remarkable strength degradation occurs due to P-�¢ effects when lateral displacements increase. The object of this study is to clarify the seismic behavior of frames by using the experimental results of tests carried on scaled RC multistory, multi-span frame models subjected to combined loading.
