Experimental and numerical investigation on cyclic behavior of Q1100 ultra-high strength steel H-section compressive-bending members about strong-axis
Q1100 refers to ultra-high strength steel (UHSS) with a nominal yield strength of 1100 MPa. Hysteretic tests were conducted on seven Q1100 UHSS H-section welded columns to assess their hysteretic performance. The hysteretic performance was evaluated through hysteresis curves, damage phenomena, energy dissipation, ductility, and load-carrying capacity. The impact of the width-to-thickness ratio and axial pressure ratio on the hysteretic behavior was also investigated. A validated finite element model was utilized to analyze the hysteresis behavior, influencing factors, and the applicability of Eurocode 3 width-to-thickness ratio limits, resulting in proposed seismic design recommendations.
期刊介绍：
Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.
Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering.
The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
