Investigations of large commercial aircraft impact effect on nuclear power plant (NPP) buildings havebeen drawing extensive attentions, particularly after the 9/11 event, and this paper aims to experimentallyassess the damage and vibrations of NPP buildings subjected to aircraft crash. In present Part I,two shots of reduce-scaled model test of aircraft impacting on NPP building were carried out. Firstly, the1:15 aircraft model (weighs 135 kg) and RC NPP model (weighs about 70 t) are designed and prepared. Then, based on the large rocket sled loading test platform, the aircraft models were accelerated to impactperpendicularly on the two sides of NPP model, i.e., containment and auxiliary buildings, with a velocityof about 170 m/s. The strain-time histories of rebars within the impact area and acceleration-time historiesof each floor of NPP model are derived from the pre-arranged twenty-one strain gauges andtwenty tri-axial accelerometers, and the whole impact processes were recorded by three high-speedcameras. The local penetration and perforation failure modes occurred respectively in the collisionscenarios of containment and auxiliary buildings, and some suggestions for the NPP design are given. Themaximum acceleration in the 1:15 scaled tests is 1785.73 g, and thus the corresponding maximumresultant acceleration in a prototype impact might be about 119 g, which poses a potential threat to thenuclear equipment. Furthermore, it was found that the nonlinear decrease of vibrations along the heightwas well reflected by the variations of both the maximum resultant vibrations and Cumulative AbsoluteVelocity (CAV). The present experimental work on the damage and dynamic responses of NPP structureunder aircraft impact is firstly presented, which could provide a benchmark basis for further safety assessmentsof prototype NPP structure as well as inner systems and components against aircraft crash.
