Structural Design and Analysis of a Super-High Building in Nanjing, China

This study analyzes a high-rise building with B-level height (i.e., total of 146.5 m) and shear wall structure. Since the project contains many plane irregularities (including 1a torsional irregularity, 1b eccentric arrangement, 2a convex irregularity), it should be treated as super building. introduces main characteristics overrun conditions describes structural design foundation basement, upper layout, force under frequent, fortified, rare earthquake actions, performance-based objectives in detail. The following measures can adopted to address problem. First, floor at thin waist structure was thickened 150 mm reinforced bilayer bidirectional patterns, reinforcement ratio no less than 0.25%. damage condition on floors great analyzed. vertical components were constrain extension edge toward top. Second, structure’s peripheral stiffness strengthened enhance anti-torsional performance minimize adverse effects irregularities. Third, using two software programs, envelope medium action dynamic elastoplastic analysis analyzed ensure safety. Fourth, constrained for columns axial-to-compressive stress strength ratios exceeding 0.3. For overall critical parts, calculated examined SATWE, MIDAS GEN, SAUSAGE packages. calculation results revealed that shows favorable anti-seismic performance, an C-level safe reliable method introduced this article promote sustainable development design.
