The result of analysis show that there is more yield hinges on the top tow storey columns of 6-storey frame7. It means that the heavy vertical load go against to the beam hinges mechanism of frame.
分析结果表明，7度区六层框架上部两层柱子出铰随竖向荷载的增大而增多，竖向荷载的增大更不利于梁铰机制的形成。
The possibility of failure caused by yield is considerable under the heavy load as high as thousands of tons. It is necessary to check the strength of the jacking frame to ensure its safety.
在高达数千吨的载荷作用下，固桩架出现屈服破坏的可能性较大，必须对该结构进行强度校核，以保证其安全性。
