Stiffener-Enhanced Steel–Concrete-Steel Sandwich Beam and Panel Under Impact
A new stiffener-enhanced steel–concrete-steel (SESCS) sandwich structure was proposed for resisting impact loading. The dynamic responses of SESCS sandwich beams and panels under low-velocity impact loading were studied. Drop-weight impact tests on SESCS sandwich beams/panels were first conducted to obtain their failure modes, impact forces and displacement responses. The impact resistance of the SESCS sandwich beam/panel was found to be significantly improved as compared to the traditional SCS sandwich beam/panel. The Finite Element model of the SESCS sandwich beam/panel under impact loading was established and validated against the test data in terms of failure mode, impact force and displacement. In addition, an analytical model was developed for predicting displacement response of the SESCS sandwich beam under impact loading. The analytical-predicted displacement responses were found to be well matched with the FE-predictions and test results.
