Dynamic Response and Bearing Capacity of Prefabricated Steel Temporary Bridges Under Heavy Crawler Vehicles on Soft Paddy Field Foundations

Dongrui Song, Zhongzheng Cui, Zhaoqing Chen, Huashun Li et autres

Many transmission tower foundations in Northeast China are built in paddy fields, requiring construction during the wet season. Currently, no temporary bridge can be quickly installed and removed to transport people, materials, and machines without destroying the fields. To solve this problem, …

New Accurate Local-Buckling Analysis of Equal-Leg Angle Steels in Transmission Towers

Dongrui Song, Xiaocheng Tang, Zhiwei Sun, Dong Han et autres

This study presents a specific analytical solution procedure to the local-buckling problem in angle steels using a two-dimensional improved Fourier-series method (2D-IFSM). The effect of coupling between the sub-plates of an angle steel on its local-buckling behaviour is studied by incorporating rotational …
