000019356 520__ $$2eng$$aFollowing the Tohuku earthquake in Japan on the 11 of March 2011 a review of the UK’s nuclear industry has been carried out using the lessons learnt from the Tokyo Electric Power Company (TEPCO) Fukushima-Daiichi station. The review concluded that there were no fundamental safety weaknesses in the UK’s nuclear industry but nevertheless, the business agreed to improve for safety critical buildings to be resilient to tornado wind generated missiles, explosion and seismic loads. In the European market, buildings that are required to perform critical safety functions have been traditionally constructed using thick reinforced concrete wall sections resulting in heavyweight structures. In addition a large footprint, labour intensive and long-time construction results in a high cost arrangement per meter square. To satisfy the requirement a new structural cladding system has been developed to absorb the high energy associated with impact, explosion and seismic loads using non-linear design techniques that consider post yield behaviour. The structural cladding system is added to the conventional architectural cladding system. The structural cladding system has been developed using a steel plate spanning between UC sections cladding rails supported by the mainframe steelwork columns. The members forming part of the structure are subjected to different beyond design basis events such as explosion, tornado pressure, tornado generated missiles and seismic loads. In order to design the structure different approaches have been followed dependent on the load case under consideration. For example the blast and impact design capacities are governed by the rotation limits while the seismic design capacity is governed by ductility limits. To obtain an efficient design an iterative process has been carried out using several push-over and time-history analyses to reach to the optimal balance between the two above requirements. The non-linear approach has enabled the design of a highly resilient building using an efficient steelwork braced frame superstructure fulfilling spatial, cost and construction requirements. The innovative and efficient solution developed can be tailored to suit alternative requirements allowing for a broad range of application where the absorption of energy by the ductile behaviour of the cladding system is required, such as in the oil and gas sector where there is potential for extreme blast combined with seismic loads.
