A series of four major loading tests (static load tests, quasi-static moving load tests, speed tests, and longitudinal load tests) was carried out. The static load test was done with the aim of obtaining the stiffness properties of the structure. The quasi-static moving load test was performed to obtain variations in deflections and strains for different positions of the load and is a confirmation of the stiffness properties. Such variations are typically determined in computational models using the well-known method of influence lines. The dynamic amplification factor and the dynamic characteristics of the bridge structure such as the natural frequencies are obtained from the speed test. The main objective of the longitudinal tests is to determine the stability of the structure when subjected to extreme horizontal loads such as from braking on the bridge or accelerating from rest on the bridge. Furthermore, the load transfer onto the bridge structure and the approaches is determined from this test.
