Static Load Test Calculation of Single Beam Based on Equivalent Stress Method

Prefabricated beams are mass-produced in the beam yard. In order to grasp the mechanical properties and deformation status of prefabricated beams, static load testing is usually the most direct and effective detection method. We are accustomed to using the equivalent bending moment method for loading calculation of bridges, but the wet joints and concrete leveling layer have not yet been poured before the installation of prefabricated beams. If this part of the load is directly equivalent to the loading load, it may cause damage to the beam due to excessive loading, and even cause safety accidents during the loading process. In view of this, taking the Zhongjiawan Bridge as the engineering background, the loading load can be reduced by 37% to 50% by calculating the stress at the bottom of the beam based on the completed state of the bridge. The beam has reasonable stress and simple loading, and the static load test can be completed by using the beam back pressure. It has certain guiding significance for single beam load tests of similar bridges.
