This paper presents a numerical investigation on seismic performance of reinforced concrete (RC) cantilever columns under unidirectional and bidirectional excitations. The influence cross-sectional geometry multiple excitations have been examined in this study. An advanced nonlinear finite element model is employed to different failure modes RC excitation. simulates degradation materials cyclic...

This paper is based on the main steel structural engineering project of Sanming Shaxian Airport Terminal. The lobby terminal building mainly composed box shaped components and BH beams. Purlins supports are made H-shaped or circular pipes other components. There 13 roof trusses located directly reinforced concrete columns in corridor, each truss connected by type joists. article introduces manu...
