Abstract

The invention discloses a method for calculating the collapse diameter of a reinforced concrete plate under the action of an explosion load, and belongs to the technical field of calculation of the collapse diameter of the reinforced concrete plate under the action of explosion. The method comprises the following steps: 1, performing explosion test on the reinforced concrete slab; Step 2, establishing a reinforced concrete plate collapse diameter calculation formula; Step 3, fitting the numerical value of the reinforced concrete plate collapse diameter calculation formula (shown in the specification); and step 4, calculating the diameter of the reinforced concrete plate collapse according to the numerical value of the reinforced concrete plate collapse diameter calculation formula. And step 4, calculating the reinforced concrete plate collapse diameter under the action of the explosion load. According to the calculation method of the reinforced concrete plate collapse diameter under the explosive load effect, the scientificity and accuracy of the calculation theory of the explosive reinforced concrete plate collapse diameter are improved, and the calculation of the reinforced concrete plate collapse diameter is time-saving, labor-saving, convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of calculating the collapse diameter of a reinforced concrete slab under an explosion, in particular to a calculation method for the collapse diameter of a reinforced concrete slab under an explosion load. Background technique [0002] As the main component of the civil engineering structure, the reinforced concrete slab bears the external load of the structure together with the beams and columns. It is considered in the prior art that under the action of the blast load, the diameter of the blast collapse of the reinforced concrete slab is only related to the proportional distance of the charges. It is incomplete to calculate the collapse diameter of reinforced concrete slabs only considering the proportion and distance of the charges; it will lead to large deviations or even serious errors in the calculation of the collapse diameter of reinforced concrete slabs. Based on the defects in the prior art, the i...
