Performance based earthquake engineering approach has been under evolution for seismic safety assessment of structures. Qualitative and quantitative definition of seismic performance levels is major challenge of concrete gravity dams. The main purpose of this article is damage patterns and failure scenarios prediction of structure while they prepare a suitable basement to determine dam seismic ...
This paper presents a progressive compression method for generic surface meshes (non-manifold and/or polygonal). Two major contributions are proposed : (1) generic edge collapse and vertex split operators allowing surface simpli cation and re nement of a mesh, whatever its connectivity; (2) a distortion-aware collapse clustering strategy that adapts the decimation granularity in order to optimi...
In this study the integrated system for progressive collapse analysis, which can evaluate the damage level of every member and automatically construct the modified structural model for the next analysis step, has been developed. The existing nonlinear analysis program code OpenSees was used as a finite element solver in the integrated system for progressive collapse analysis. The developed inte...
