Abstract : Abstract - Laced Steel-Concrete Composite (LSCC) system consists of perforated steel cover plates, which are connected using reinforcing members and cross-rods, and in-filled with concrete. Experimentally, it has been demonstrated that the LSCC beam possesses high rotational capacity, which makes it suitable for structures resisting suddenly applied loads, such as blast loads. The LSCC slab is developed by integrating the individual units of LSCC flexural units through provision of continuous cross-rods. In this paper, towards understanding the blast response behaviour of LSCC system, numerical investigations are carried out on LSCC slabs subjected to blast loading. Finite element model of the LSCC slab is generated using a combination of solid, shell and beam elements. The response of the LSCC slab system to blast loads is obtained by using finite element analysis software ABAQUS. Dynamic explicit analysis is carried out. Peak displacement at centre is extracted and used as response parameter to demonstrate the effectiveness of the LSCC slabs on the blast resistance capacities. Its performance has been numerically demonstrated to be better than other forms of slabs in resisting blast loads by comparing with some results available in the literature. Parametric studies are carried out on the LSCC slab subjected to blast loading. Steel plate thickness, concrete grade, diameter of lacings and diameter of cross-rods are varied to study their influence on the response of behaviour of slab. From the numerical investigations, it is found that plate thickness significantly affects the response than the cross-rod diameter and lacing diameter for same grade of concrete.
