Abstract
This paper presents a research study about timber shear walls, with materials commercially available in Costa Rica. With new developments in engineered timber, the Costa Rican Seismic Code included a chapter on timber structures, defining diaphragms and shear walls as part of the lateral resisting system. A research study was then carried out, with the objective of determining the structural behavior of a typical shear wall. Twelve specimens were constructed and tested, varying the nail spacing and anchorage system. The specimens were tested with monotonic and cyclic loading procedures according to ASTM E564 and ASTM E2126 respectively. It was found that the specimens can develop an adequate shear strength and stiffness if the end studs are adequately anchored to the foundation. These results are an important input for the Costa Rican Seismic Code and for the development of engineered timber in Costa Rica.
