Abstract: The strength of flammable gas cloud explosion has been experimentally researched by means of acetylene-air clouds which were ignited by electric sparks.The ignition device which provides ignition energy of about 100mJ was made according to international standard ISO 6184 and American Standard NFPA68. The explosion pressure was picked up by pressure transducer with a dynamic responding time of 0.001 s and recorded by computer. By regressing the experimental data,the relationship of gas cloud explosion pressure to the initial radius of gas cloud and the distance to the center of gas cloud can be obtained. That is p=Ar 2 0/r where A is a constant depending on flammable gas cloud.The damage of unrestricted gas cloud to building structure is discussed based on the strength of houses.
