Paper Title:
Experimental Study on Impact Resistant Performance of Steel Beams
  Abstract

Impact damage of building structures occurs frequently nowadays, and failure of key components of the structures may lead to the collapse of the whole buildings which could cause serious consequences. Thus, it is necessary to study on the impact resistant performance of the members. The different protective measures against impact loads were examined through the experimental testing in this paper. A tube steel beam with the rectangle cross-section was selected as the tested object. During the experimental testing, the different weight of the drop hammers and the different shapes of the contact surfaces were designed for sake of comparison. The strain history at the middle span of the steel beam under the impact load was measured by a Fiber Bragg Grating sensor. By comparing the strain values, the experimental results show that the composite layer which consists of the rigid and the flexible plate is superior to the single layer which only consists of the rigid plate, and have a better effect for suppression of the dynamic response against the impact loads.
