THE IMPROVEMENT OF BEHAVIOR TO VERTICAL FORCES FOR STRUCTURAL ROOF ELEMENTS BY RECONFIGURING THE STATICS SCHEME. CASE STUDY

Abstract

The service level of safety is a main indicator for a building’s structural performance. The non-fulfilment factors of this criterion are multiple. An important component is constituted by the increase of the loads intensity. In this context, the case study presented in this paper was conducted on a industrial building “type ground floor” and highlights the growth of strains in the roof trusses elements, higher than the initial ones witch ware considered, as a result of modification of prescriptions contained in the norms for vertical loads evaluation. In this situation, the fulfilment of the service safety to vertical loads was considered to be ensured by trying to redistribute the strains as a result of changing the supports.
