A ground slab in a factory at Suksawat road, Samut prakan has been tested by load testing. In design point of view, slab on ground is normally designed by linear spring distribution support assumption. However, In real situation, slab on ground experiences nonlinear behavior. There are many inconsistent factors such as temperature, water absorption, ground depth, and soil component. Their factors affect to support behavior in each area of slab uncertainly.
The roof structure was insufficient for a new ceiling load requirement in accordance to FEM analysis, thus, strengthening solution was provided, and load test was carried out lately to verify the safety of the structure since its very important meeting room of an international organization. As a result, the strengthened roof is satisfactory the new load system. Water barrels were used as load application to the roof, dynamic data logging system was used to capture displacement of critical members.
Resotion engineering team operated load tesing in one factory in Bangpa-in industrial estate. The factory have to install new heavy machine so they required to check floor capacity before. This load testing used 100 kg concrete cube for applying load 6 tons per square meter (total load 22 tons). Measurement system collected deflection data by 9 dial gauges and 3 displacement transducers.
