Abstract

Abstract

A kind of cross laminated timber (CLT) wall-to-floor joint with angle brackets was studied. Firstly, the smooth-thread shear, transverse shear, withdrawal resistance and failure modes of two self-tapping screws in CLT plate were studied to estimate the bearing capacity of the CLT wall-to-floor joints with angle brackets. Then monotonic loading test and cyclic loading test in both directions of uplift and shear were conducted on the joints. The main failure modes were bending of the screws and the compressive failure of wood. The results showed that the connection had good ductility and energy dissipation capacity.
