Experimental and numerical research is being performed to evaluate the performance of self-tapping wood screws for use in steel-timber composite construction. Cross-laminated timber (CLT) was fastened to a hot-rolled wide flange steel beam using self-tapping wood screws. Extensive pushout testing was performed. In addition, four-point bending testing was conducted. The beam test results are compared against a steel-timber fiber model, existing equations adapted from steel-concrete composite design and experimental steel-CLT load-slip response from pushout testing.
