AI Technical Summary

Problems solved by technology

All non-military civil engineering projects have been classified into this category. The explosion damage test of civil engineering is an important means to explore the structure under load. The explosion is a special load, and the main feature is the local shock wave in a short time. Excitation is different from the static properties of structural dead load, and also different from the full-structure excitation of seismic load and dynamic load. Due to the danger of explosion experiment itself and the strict control of drug circulation, explosion experiments in the field of civil engineering structures are seldom carried out. Most of the experiments carried out are based on chemical and pharmaceutical experimental platform devices. At present, no loading platform method for structural experiments in this field has been developed, which seriously restricts the experimental research on the performance of civil engineering structures such as beams, slabs, and columns under the action of explosions.
