President, Wyoming Test Fixtures Inc. In my October 2015 column, I compared three V-notched shear test configurations used to measure the shear stiffness and shear strength of composite materials: The ...

A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that ...

This project aims to develop and validate bolted splice details for C-PSW/CF, a structural system designed for non-seismic regions like New York City and Boston. The focus is on areas where bolted ...

This technique is implemented in Textechno’s FIMATEST system. Dr. Ulrich Mörschel, CEO of Textechno, explains: “Up to now, a characterization of the interfacial shear strength according to standards ...

Compared to traditional structural materials, polymer matrix composites (PMC) offer greatly enhanced performance and flexibility. However, these benefits come at the cost of increased material ...

Say we consider a beam made up of thin layers (laminae) aligned with the longitudinal axis of the beam, and for which the laminae can slide with respect to each other along the longitudinal axis as ...

The American Wood Council recently released the results of full-scale tests of cross-laminated timber (CLT) diaphragms. The findings indicated that the connections performed better than expected, ...

The transverse load P will produce a shear force V in the positive y direction on a mathematical cut through the beam at point “a”. This shear force is directly responsible for the shear stress τ on ...
