Guidelines for component-based analytical vulnerability assessment of buildings and nonstructural elements

Technical Reports | 29 Feb 2016 > A procedure is offered for the analytical derivation of the seismic vulnerability of building classes, that is, probabilistic relationships between shaking and repair cost as a fraction of replacement cost new for a category of buildings. It simulates structural response, damage, and repair cost for the structural and non-structural components that contribute most to construction cost, and then scales up results to account for the components that were not simulated. It does so for a carefully selected sample of building specimens called index buildings whose designs span the domain of up to three features that are believed to most strongly influence seismic vulnerability within the building class. One uses moment matching to combine results for the index buildings to estimate behaviour and variability of the building class. One can simulate non-structural vulnerability alone by ignoring damage and repair cost for structural components. The work is written for a structural engineer with a master’s degree, skilled in structural analysis, but not necessarily experienced in loss modelling.

GEM Faulted Earth Project

Technical Reports | 10 Sep 2015 > This is the final report of the GEM Faulted Earth Project (GFE), which was active between 2010 and 2013.

Guidelines for Analytical Vulnerability Assessment - Low/Mid-Rise

Technical Reports | 25 Aug 2015 > Guidelines (GEM-ASV) for developing analytical seismic vulnerability functions are offered for use within the framework of the Global Earthquake Model (GEM). Emphasis is on low/mid-rise buildings and cases where the analyst has the skills and time to perform non-linear analyses.

Introduction to the GEM Earthquake Consequences Database (GEMECD)

Technical Reports | 25 Mar 2015 > From the inception of the GEM Global Earthquake Consequences Database (GEMECD) the ambition was that the database will serve to inform users on consequences from past events, as a benchmarking tool for analytical loss models and to support the development of tools to create vulnerability data appropriate to specific countries, structures, or building classes.
