Experimental Behavior of L-Shaped and T-Shaped Cross-Laminated Timber to Evaluate Shear Walls with Openings

There is increasing interest in using cross-laminated timber (CLT) buildings because of its high strength and stiffness. In Japan, structural design guidelines for CLT were established 2016 construction mid-rise increasing. Wide-panel walls can exceed widths 10 m integrate cut-outs window door openings. However, under lateral loads, corner cracks at the openings have been most prevalent failure mechanism. To investigate initiation propagation cracks, a series bendings are undertaken on L- T-shape specimens extracted from panels. addition, three-point bending shear tests also carried out beam sections Three types brittle observed: or column, rolling failure.
