Discussion on the optimum configuration of section steel for the middle seismic tensile stress of the shear wall of an over-limit high-rise civil building

Abstract

A super high-rise civil building was originally designed with a relatively large area of shear wall section steel configuration, coupled with the configuration of steel bars, resulting in the construction of the project more difficult. To solve this problem, PKPM was used to build the model to extract and calculate the tensile stress of inflexible wall limbs under moderate earthquakes, and the configuration of the section steel in the original design was analyzed. An in-depth interpretation of the “Technical Points for Special Examination of Seismic Fortification of High-rise Buildings Exceeding Limits” (Jianzhi [2015] No. 67), Chapter 4, Article 12, Paragraph 4, on the provision of shear wall section steel configuration was conducted. Finally, based on the original design, an optimization criterion for the configuration of the section steel in the wall was proposed.
