Seismic performance and deformation characteristics of low-rise SIP panel timber buildings

This article discusses the seismic resistance of the two-story structure constructed from wooden SIP panels, which are commonly used in low-rise structures. In the research process, the behavior of the building under seismic influences was comprehensively analyzed based on theoretical calculations and digital modeling performed using the ETABS software package. In particular, the values of horizontal displacements along the floors of the building were determined, and the results of theoretical calculations were compared with the results obtained in the ETABS program. In addition, the stress–strain state of the building structures was determined, and deformations arising under seismic loads, internal forces, and the laws of their distribution were assessed. The obtained results show that wooden buildings with SIP panels are sufficiently deformable and energy-absorbing in relation to seismic impacts. The convergence of the results of theoretical and numerical calculations confirms the reliability of the chosen computational models and accepted assumptions.
