Experimental study and numerical analysis on unidirectional seismic performance of square steel tube glulam composite columns
This article takes STC long and short columns as the research objects, and first conducts quasi-static tests to preliminarily explore the failure characteristics of STC long and short columns under horizontal reciprocating loads. Then, a large number of numerical analysis models are established to explore the influence of coaxial compression ratio, steel pipe wall thickness, wood cross-sectional area, and bending point height on the seismic performance of STC long and short columns through numerical analysis. The results indicate that although the trend of changes in STC long columns and short columns under these factors is the same, STC long columns mainly resist bending and compression, while STC short columns mainly bear shear and bending resistance. Finally, the calculation formulas for the compressive bending bearing capacity of STC long columns and the shear bending bearing capacity of STC short columns were derived through theoretical analysis. The accuracy and safety of the formulas were verified through a large number of numerical simulation results.
期刊介绍:
Advances in Structural Engineering was established in 1997 and has become one of the major peer-reviewed journals in the field of structural engineering. To better fulfil the mission of the journal, we have recently decided to launch two new features for the journal: (a) invited review papers providing an in-depth exposition of a topic of significant current interest; (b) short papers reporting truly new technologies in structural engineering.
