Abstract

Mass timber structures have been utilized in North America, Europe, and Oceania, and are being evaluated in Latin America to decrease the housing shortage and the construction industry's contribution to greenhouse gas emissions. In Chile, where seismic activity is common, it is crucial to provide resilient timber structures that safeguard life safety and reduce earthquake-induced damage and repair costs. The Performance-Based Earthquake Engineering (PBEE) framework offers a practical alternative for designing more efficient timber buildings and assessing the risks related to seismic hazards, potential damage, and economic losses. In this paper, the PBEE framework is employed to assess the likelihood of a government-subsidized 5-story cross-laminated timber building collapsing under seismic stress in Chile. The probabilistic seismic hazard analysis (PSHA) was used for hazard site characterization, and the collapse probability analysis indicated a probability of less than 0.1% for a building with the mentioned characteristic, making it suitable for construction in Chile. Further research is required to achieve loss estimation under the PBEE framework, such as quantifying damage fragility curves of representative engineering details for Chilean construction.
