Abstract Typically, the mechanical behavior of CLT shear walls for lateral loads is assumed to be governed by the wall base connections, such as hold-downs and angle brackets. However, many experimental and numerical studies available in literature have shown that in “box type” CLT buildings, the connections between perpendicular walls contribute to the lateral response of the CLT shear walls. This study presents the results of an experimental campaign aimed at investigating the lateral performance of CLT shear walls connected to perpendicular walls. Two CLT wall assembly configurations were tested: single Shear Wall configuration (SW), which considers a single CLT shear wall subjected to lateral load, and Shear Wall connected to Perpendicular Wall configuration (SW+PW), which considers a CLT Shear Wall connected to a Perpendicular Wall subjected to lateral load. Results showed that the SW+PW configuration reached higher structural performance in terms of lateral stiffness and lateral capacity than single SW configuration. This increase of lateral performances is governed by the properties of the wall-to-wall connections as well as the properties of the hold downs used in the perpendicular walls. Results of this experimental study show that the perpendicular walls and wall-to-wall connections may be included in the design models of CLT shear walls subjected to lateral loads. © 2022 The Authors.
