Roof trusses are used to carry gravity loads. The shelters are made from wood and have a light gauge galvanized corrugated steel roof. Outside walls of the shelter are initially covered with a tarp fabric, allowing for future expansion to a larger size as resident's resources allow. 1 shows front and side elevations of the shelter which has dimensions of 4.1 m by 3 m by 4.1 m of height. The first author, who served as the consulting engineer in the design phase, was motivated to study the shelter more in-depth given the non-conventional structural system used and the extreme wind load demands that these could potentially experience. While shelters of many different forms and materials were used, this study focuses on a wood shelter for which nearly 1100 units were built in the Municipality of Dulag. In response to the humanitarian crisis several NGOs provided shelter to those who lost their homes. Introduction On November 2013, super typhoon Haiyan hit the Philippine Islands of Samar and Leyte with winds exceeding 300 km/h, displacing tens of thousands of people (USAID, 2014). Keywords: Transitional shelters Full-scale testing Wind loads Wood construction Disaster reliefġ. Results from individual EPBs confirmed the full-scale test observations. This finding motivated further evaluation of the EPBs. The test was stopped when significant uplift deformations of the elevated post bases (EPBs), used to anchor the shelter columns to the concrete foundations, were observed at the columns in tension. The shelter's capacity was higher than the design demand, confirming the analytical results. The main goals of the experiment were to confirm analytical results, and to determine failure mechanisms, lateral stiffness and the lateral capacity. Because of the non-conventional lateral force resisting system used in the shelter, a full-scale test under simulated lateral wind forces was performed. The structure is composed of a timber braced frame with a galvanized steel roof. The shelter studied is of a transitional nature, with initial floor dimensions of 4.1 m by 3 m, but allowing for expansion. This paper presents an experimental study performed to verify the structural capacity of one particular shelter. Several relief organizations facilitated construction of thousands of shelters. On November 2013, typhoon Haiyan devastated parts of central Philippines, creating a need for shelter for the thousands of residents displaced.
