Abstract: As a high-performance structure, the concrete-filled steel tubular (CFST) structure has become one of the preferred structural forms for China’s current major civil engineering constructions. This report will present the nonlinear confinement effect of CFST structures, the life-cycle-based constitutive models of the core concrete, and the calculation framework for the resistances of CFST members. Concepts, main forms, and the life-cycle-based analysis and design framework for CFST hybrid structures will also be presented. Subsequently, the applications of the research outcome in the main structure design of several iconic constructions, including the CITIC Tower, the Canton Tower, and the Ganhaizi Mega Bridge, will be elaborated. Finally, the National Standard of China and the ISO standard for CFST structures will be introduced.

Abstract: The unexpected collapse of burning buildings has been a major killer of firefighters, since current techniques are very hard to accurately evaluate the collapse risk of a real building in fire. Developing a practical approach for early-warning fire-induced collapse of steel buildings in real-time is an urgent need, as these buildings account for a large part of collapse accidents due to severe degradation of steel mechanical properties at elevated temperatures in fire. The uncertainties of a burning building, such as load levels and heating conditions which differ from designed values, and the real-time acquisition of its structural responses to fire are two challenging issues need to be addressed. Through parametric analysis of collapse mechanisms considering uncertainties in real fire, the limited potential collapse modes of steel portal frames and steel trusses porpularly used for steel buildings are identified. Displacement responses of the burning building at key positions of the building structure, identified as Key Physical Parameters (KPPs), are selected for early warning fire-induced building collapse, as these displacements exhibit unique variation patterns for each collapse mode. Three-level early-warning strategy is proposed based on evolution laws of KPPs during the process of the building collapse. As some KPPs are hard to be measured directly in fire scene, especially for those located on the roof or inside the building, real-time acquisition method of the hard-to-measure KPPs through easy-to-measure data are investigated. Considering the close correlation between rotations and displacements at structural nodes at definite temperatures, pre-embedded thermocouples and inclinometers, which are easily employed in practice, are proposed to facilitate the real-time acquisition of hard-to-measure KPPs. Real fire tests have been conducted to verify the effectiveness of the approach for early-warning fire-induced collapse of steel portal frame and steel truss buildings.

Abstract: This keynote paper reflects on the key foci in the area of the mechanics of structures and materials in the past, present and future. The paper commemorates the First Australasian Conference on the Mechanics of Structures and Materials (ACMSM) at The University of New South Wales from August 21-23, 1967. The paper then reflects on the key issues in the area of the mechanics of structures and materials at present and posits what will be some of the key issues for the future. Using the area of steel-concrete composite construction, the issues of the mechanics of structures and materials will be further highlighted in relation to real applications in the past, present and future.

Abstract: This lecture explores how controlled rocking, rolling isolation, and rotational inertial devices are reshaping dynamic control strategies for building structures, with special focus on their application to modern timber systems. It examines how stepping away from traditional fixed-base assumptions, embracing motion, and harnessing inertial forces to our advantage can enable efficient, low-damage solutions for seismic protection. The talk will delve into the fundamental mechanics and emerging engineering concepts behind rocking and rolling systems, highlight the role of inerters as force amplifiers and "size shifters," and demonstrate how their integration enhances seismic performance. Special emphasis will be laced on how these strategies are unlocking the seismic potential of engineered timber structures. Drawing on recent advances in numerical modelling and experimental earthquake engineering, this lecture invites you to view seismic control not as a battle against motion, but as a carefully choreographed rock ‘n’ roll performance allowing timber to play a starring role in the next generation of resilient, sustainable structures.
