Experimental study on adaptive-passive tuned mass damper with variable stiffness for vertical human-induced vibration control

Liangkun Wang et al.

Summary: In this study, an adaptive-passive variable stiffness tuned mass damper (APVS-TMD) is proposed to solve the mistuning problem of a passive TMD. The stiffness and frequency of the APVS-TMD can be retuned by changing the length of the cantilever beam and adjusting the air gap between the conductor plate and magnets. Numerical simulation and experimental verification show that the APVS-TMD can accurately identify the decoupled structural natural frequency and effectively control human-induced vibrations.

A systematic review of factors affecting post-disaster reconstruction projects resilience

Shawn Hezron Charles et al.

Summary: This study focuses on resilience factors in post-disaster reconstruction projects and develops a conceptual framework to guide their strategic selection and application. Through systematic review, it identifies 24 resilience factors grouped into five criteria, including governance, innovations, reconstruction approaches, resource management, and stakeholder expectations. The findings emphasize the importance of client and end-user participation in construction management and highlight the need for a comprehensive approach to resilience in the built environment.

Seismic performance improvement of base-isolated structures using a semi-active tuned mass damper

Liangkun Wang et al.

Summary: This paper presents a semi-active tuned mass damper (STMD) with variable stiffness and damping to improve the aseismic performance of passive base-isolated structures. The STMD is applied to both linear and nonlinear base-isolated structures, showing excellent control effect and effectively improving displacement and acceleration performances.

Post-disaster recovery in urban and rural communities: Challenges and strategies

Elnaz Safapour et al.

Summary: This study categorizes and analyzes the barriers to successful housing reconstruction after natural disasters around the world, providing strategies for effectively addressing these barriers. The outcomes of the study will help decision makers to identify barriers in a timely manner, allocate resources effectively, and improve post-disaster reconstruction performance in rural and urban communities.
