SEISMIC RESISTANT PERFORMANCE ANALYSIS ON AN UNSYMMETRICAL SUPER-HIGH STEEL TV TOWER
Linyi TV tower located in Linyi, Shandong province is an unsymmetrical steel TV tower of 326m in height. Its main body is a circular hollow section (CHS) with big diameter which is supported by a curved truss laid in spirality. Based on the case study of this unique steel TV tower, both conventional earthquake time-history response analysis and rare earthquake nonlinear time-history response analysis of the structure are made to evaluate the seismic behavior of the tower such as weak spots and weak degrees. The results show that the seismic resistant performance of this structure is good. A few points on the tower need to be paid more attention under strong earthquake. The structure meets the requirements of no-damage under light earthquake, repairable under medium earthquake and no-collapse under strong earthquake.
