Experimental study on lateral performance of glued-laminated timber frame infilled with cross-laminated timber shear walls
Highlights Lateral performance of glued-laminated timber (GLT) frame infilled with cross-laminated timber (CLT) shear wall was researched. The influence of opening size, type (door, window) and thickness ratio of CLT wall on the lateral performance of this structural system were investigated. The collaborative working mechanism of GLT frame and CLT wall was obtained. Research results provide references for the code revision of inter-storey drift and seismic response of this structural system.
Abstract This paper presents the results of a lateral performance study on glued-laminated timber frame (GLT) infilled with cross-laminated timber (CLT) shear walls by means of experimental method. Specially-designed steel connectors were installed at the frame-to-wall connections, which are used to provide reliable mechanism of force transmission for the structure. Lateral cyclic loading tests on this structural system were conducted, and the influences of opening size, opening form (e.g., door and window), and aspect ratio of wall panels on the lateral performance of the structural system were examined. The elastic and elastic–plastic drift ratios of the GLT frame infilled with CLT walls were defined as well. In addition, the failure mechanisms, hysteretic characteristics, lateral stiffness, energy dissipation and bearing capacities of the GLT frame with CLT shear walls were investigated in details, and the collaborative mechanism and lateral collaborative effect between GLT frame and CLT shear wall was evaluated. Results indicated that the inclusion of the CLT shear wall improved the overall stiffness and strength of the GLT frame significantly, and increments were 10.66–14.1 and 2.74–5.26 times, respectively. The CLT shear walls played an important role in dissipating a considerable portion of energy in the initial loading stage. When the overall GLT frame reaches the peak strength, observable damage appears on the walls, like cracking or squeezing deformation, but the structure is still able to withstand a substantial part of horizontal loads.
