The roof structure of a meeting room was insufficient for a new ceiling load requirement according to the FEM analysis. Thus, strengthening solution was provided, and a load test was carried out to verify the safety of the structure as this is a very important meeting room of an international organization.
A 4-point bend test was conducted on five patterns of metal sheets (totalling 30 samples). The testing equipment has been developed to test a specimen with a wide surface area with the maximum load carrying capacity of 3 tons. The proof load and the maximum load were recorded and converted into uniformly distributed load. Also, the relationship between the load and the deflection was reported in the test results.
Structural renovation has become more and more common in recent years. Due to the high concentration in urban areas, most land has already been occupied by existing structures which later on may be renovated for different uses. However, due to deterioration over time or lack of maintenance, many existing structures may not be in a good condition for renovation which can then raise safety concerns. Thus, a load test is deemed necessary.
The Pull Out Test is one of the methods used to inspect an anchor’s load carrying capacity. This test determines the tensile strength capacity. The tested load will be applied in the parallel direction to the anchor using a hydraulic pump with a load measuring system. Displacement of the tested anchor is measured by a displacement transducer which shows real-time data. The Pull Out Test conducted by RE complies with the ASTM E488-10 standard.
