Impact of torsion on the seismic resistance of common buildings with rigid horizontal diaphragms. Application to wooden structures
type: Dataset
description: The earthquakes are natural disasters affecting the earth's crust, which can have major destructive effects in urban areas. We have a set of scientific, technical and conception knowledge which allow to « build earthquake-resistant », but these methods must be adapted to simple buildings. The development of earthquake-resistant regulations (Eurocode 8 and national annexes) and seismic zoning of France evolve significantly to the need for taking into account the seismic action in the building design. In seismic design, it is essential to take into account the torsion effects that can lead to serious consequences in terms of damage to civil engineering structures. This research work presents a process including different levels of approach to take into account the effect of the torsion. The structures particularly targeted by this work are the so-called soft frames and more specifically the timber buildings. After a course of bibliographic elements related to the timber structures and the structures of current buildings subjected to seismic situations, a parametric study is taken with a method for multi-dimensional combination in order to analyze the influence of different bracing configurations on the sensitivity of the structure to the torsion phenomena. This first stage is based on the adaptation for timber structures, in the context of Eurocodes (structural torsion and accidental torsion), of a New Zealand method developed by Paulay and Priestley originally proposed for reinforced concrete buildings. The study of the behavior of timber buildings in seismic situation is part of an approach using the equivalent linearization method by a behavior coefficient. So the seismic action can be modeled by equivalent static forces which are then transmitted to the vertical structural elements by horizontal diaphragms. The objective of this work is to define the distribution of seismic forces on each brace with the inclusion of torsion from cartography of bracing and masses i…
