Structural design and analysis of large-scale indoor equipment for blast test
Jun Wu · Journal of PLA University of Science and Technology · 2007
In order to realize experimental investigation of explosive phenomena, blast-resistant performance of structure or material at stable environment,the large-scale equipment used for indoor blast test was designed with vibration reducing method.The equipment is a half-closed multiple layered underground structure,which is made up with steel,reinforced concrete and sand layers.The blast-resistant performance of the equipment was analyzed based on one-dimensional elastic plane stress wave theory and research of the layer-crack and collapse of the multiple layered structure was carried out.The results show that the equipment can satisfy the demand of engineering blast-resistant test.
