Test study on eccentric compression of light steel concrete L-shaped composite column in modular wall prefabricated building
Abstract This paper aims to investigate the eccentric compression mechanical properties of light steel concrete L-shaped composite columns of prefabricated modular walls. Nine groups of full-length columns were tested under eccentric loading, considering four parameters: eccentricity, eccentric angle, length and steel thickness. The experiment revealed that the composite columns had high vertical bearing capacity and deformation capacity. All the specimens experienced tensile failure and the MSEA and LSEA specimens failed with obvious lateral deformation. The failure of the specimens was mainly caused by the crushing of the concrete and the buckling of the steel skeleton and reinforcement. Thorough the analysis of the load-displacement curves, the lateral deformation curves and the strain development curves, insights into the mechanical properties were obtained. The results show that eccentricity has the most significant impact on the peak bearing capacity, which decreases as the eccentricity increases. Reducing the steel thickness can improve the ductility of the specimen to a certain extent. During the compression process, the steel skeleton, longitudinal bars and concrete exhibit effective cooperation. The stress distribution within the specimen is reasonable, and the middle section of the column conforms to the plane cross-section assumption. The analysis results are consistent with the experimental behaviors.
