Abstract

The present invention discloses a method for determining the equivalent static load of the blasting action of the RC beam with lifting wave reinforcement. The method comprises the following steps: (10) acquisition of the static bearing capacity parameters of the component: acquiring static bearing capacity parameters of the component through the quasi-static uniform loading test of the RC beam with lifting wave reinforcement and the quasi-static uniform loading test of the RC beam with the with lifting wave reinforcement of the two-end lifting wave; (20) estimation of the resistance dynamic coefficient: according to the static bearing capacity parameters of the component, estimating the dynamic resistance coefficient of the RC beam; and (30) equivalent static load calculation: according tothe resistance dynamic coefficient, calculating to obtain the equivalent static load of the blasting action of the RC beam with lifting wave reinforcement. According to the method for determining theequivalent static load of the blasting action of the RC beam with lifting wave reinforcement disclosed by the present invention, the error between the calculation result and the actual situation is small.

Description

technical field

[0001] The invention belongs to the field of anti-explosion technology of structures and components, in particular to a method for determining the equivalent static load of an RC beam with wave reinforcement and explosion effect with little error from the actual situation. Background technique

[0002] Sometimes it is inconvenient or even impossible to carry out explosion simulation or test directly on wave-reinforced RC (Reinforced Concrete, reinforced concrete) beams. In order to provide the most important input parameters for the equivalent static simulation or test of RC beams with corrugated reinforcement, the blast load needs to be equivalent to the static load.

[0003] In order to obtain the equivalent static load of the blast load, it is first necessary to determine a crucial dimensionless constant when scaling the blast load—the dynamic coefficient of resistance.
