Public buildings that house large populations are easy targets for terrorist attacks, the primary issue of architectural blast-resistant design is how to get blast loads on the surface of structures, and the shapes of blast waves and buildings both have important effects on it. In this paper, experiments and numerical simulations were carried out on blast loads on the surface of the cylindrical shell. blast loads, detonation products, and blast waves were well recorded and simulated, blast loads at the edge of cylindrical shells were attenuated by about 75%, and vortex rings were accidentally photographed nearby. blast loads are much affected by the location of the detonation point, charge shape, and charge size. The original shape of structures rather than deformation determines the distribution of blast loads, the air viscosity also needs to be scaled when using a scaled model to test blast loads. Experimental and simulation methods can offer a reference for building a standard database of blast loads.
