本文提出采用拟动力试验方法解决爆破工程和防护工程中由于炸药爆炸和核爆炸地震动而引起的安全问题和结构抗震问题,并提出采用该方法时应解决的爆炸地震动的设计反应谱和爆炸地震动人工模拟的反应谱拟合技术。

RESPONSE SPECTRUM COMPATIBLE WITH EXPLOSIVE GROUND MOTIONS

This paper presents a method of pseudo-dynamic test which could resolve problems of safety and vibrational proof of structures in the explosive and proofing engineering that results from ground motions by explosion.It also presents the design of the response spectrum of the explosive ground motion and its compatible technique with the response spectrum.The approach on generating artificial accelerograms presented here is on the basis of approximate relationship between the acceleration response spectrum and its power spectrum.The method of pseudo-dynamic test of structure by computer-actuator on-line system is a new experimental method. It can reflect the actual seismic behavior and dynamic response of structures under earthquake motion and can test large scale models as well as full size structures.
