Performance-Based Plastic Design Method for Cross-Laminated Timber Shear Wall Structures

Abstract

Reinforced concrete is widely used in construction, but its production requires large amounts of natural resources and causes environmental impacts. This study investigates the use of Cross-Laminated Timber (CLT), made from fast-growing timber species, as an environmentally friendly alternative. CLT panels are used to form shear walls, which are key elements in resisting lateral loads during earthquakes. This research applies the Performance-Based Plastic Design (PBPD) method, together with the National Design Specification for Wood Construction (ANSI/AWC NDS), to design and evaluate the shear performance of CLT walls. Case studies include buildings with 5, 10, and 15 stories located in Mueang District, Kanchanaburi Province, with seismic loads determined according to the 2021 Ministry of Interior regulation. The objective is to develop a practical design for the anchorage system of CLT walls and to create a modeling approach that can support seismic-resistant timber buildings in the future.
