The relationship between the ground motion intensity measure (IM) and the engineering demand parameter (EDP) is analysed in the paper so as to identify and define the most efficient EDP-IM relationships for RC high-rise buildings. A 30-story RC high-rise building with the core wall structural system was selected as the reference building. 240 nonlinear time-history analyses were conducted for 6...

the nonlinear static pushover analysis technique is mostly used in the performance-based design of structures and it is favored over nonlinear response history analysis. however, the pushover analysis with fema load distributions losses its accuracy in estimating seismic responses of long period structures when higher mode effects are important. some procedures have been offered to consider thi...

The vertical component of ground motions is known to cause severe damages certain structures. Long span cable-stayed bridges are among those vulnerable structures due their high mass and cables that take no compression. In this paper, the earthquake effects on several have been investigated using 3-D nonlinear time history finite element analyses. Different main lengths, pylon shapes pylon/deck...

Additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. In this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...

Abstract Two models of the 10-story reinforced concrete building tested at E-Defense laboratory in 2015 are built: F model, which nonlinear behavior is distributed over element length, and H lumped plastic hinges with a moment-chord rotation response assigned based on empirical formulations proposed literature. Nonlinear time–history analyses performed to reproduce experimental shaking-table te...

The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure.  For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered.  Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...

Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...

In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...
