Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

Failure under seismic action generally occurs in the form of out-of-plane collapses walls before reaching their in-plane strength historical stone masonry buildings. Consistent finite element (FE) macro modeling has emerged as a need for use assessments these walls. This paper presents numerical model calibration U-shaped multi-leaf wall specimens tested ambient vibrations and (OOP) load revers...

The seismic safety of existing building stock has become a very critical issue in recent years, mainly earthquake-prone South Europe where most the buildings were designed before enforcement standards. Therefore, concept, development and testing efficient cost-effective retrofitting technologies are nowadays strongly needed, both for society scientific community. This study deals with assessmen...

Abstract School buildings being a critical social infrastructure, assessment of their seismic behaviour is utmost importance in ensuring safe schooling facilities locations high seismicity. This study presents two important aspects analysing any existing building stock for behaviour: the development an appropriate taxonomy system and analytical method to conduct fragility assessment. A detailed...

The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...

High-rise buildings have been rapidly increasing worldwide due to insufficient land availability in populated areas and their primary role as essential modern cities capitals. However, high-rise are very complicated the huge number of structural components elements unlike low-rise buildings, well these demand high stability for safety design requirements. This paper aims provide brief informati...

in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....

endurance time (et) method is a relatively new performance-based earthquake method for structural evaluation and design. in this method, the structure is subjected to a gradually intensifying accelorogram(s) and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. using moment-resisting and braced frames which are rehabilitated by...
