Abstract Due to technological developments in last decade, new methods of seismic evaluation are use like simulation based, algorithm probabilistic, software based etc. These have enabled researchers move from linear non-linear analysis. Incremental dynamic analysis (IDA) is performance method where a suite ground motions applied structure further scaled particular levels intensity. Seismic fra...

The seismic evaluation of existing buildings is a more troublesome assignment than the design new buildings. need for becomes necessary to know level structural damage and how cure it due earthquakes. shows structure’s behavior under loads determines ultimate capacity structure, there are several methods used in assessment analysis which may be static or dynamic. In this study, an educational b...

Improving design of new buildings and retrofitting existing build, to resist the action earthquakes, constitute an issue primary importance. Among emerging techniques that can be used for this purpose, reinforcing with ferrous based shape memory alloys has given promising results. These materials are cost-effective; they have excellent recentering capabilities, high damping properties elevated ...

Superelastic Shape Memory Alloy (SMA) is accepted when it used as connection in steel structures. The seismic behaviour of steel frames with SMA is being assessed in this study. Three eightstorey steel frames with different SMA systems are suggested, the first one of which is braced with diagonal bracing system, the second one is braced with nee bracing system while the last one is which the SM...

In this study, an existing hospital structure has been evaluated with incremental dynamic analysis (IDA). This building is accommodated in Karaj with soil type II. At first, two 2-D frames along X, Y direction are selected. Then, five performance levels are determined according to “Rehabilitation Code for Existing Buildings (Publication No. 360) including Immediate Operational (IO), Limited Dam...

The effects of Dextra Groutec couplers on the global performance precast reinforced concrete frames are investigated by comparing criteria conventional RC structures to that said such elements connected end-to-end using these couplers. As provide continuity reinforcement, this mechanism can perform as a unit, and entire structural system be considered emulative long is comparable conventionally...
