In the current research, elastoplastic behaviour of symmetrical and asymmetrical reinforced concrete buildings is explored by dynamic analysis. The used ground excitations are sequential type, which found in literature to possibly strongly affect structural behaviour. contemporary seismic codes neglect impact earthquakes on response, highlighting a scientific gap necessary be studied. Within sc...

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

An integrated seismic monitoring system with a total of 55 channels of accelerometers is now operating at and in the nearby free-field site of the 20-story steel-framed Atwood Building, in highly seismic Anchorage, Alaska. The building has a single-story basement and a reinforced-concrete foundation without piles. The monitoring system comprises a 32-channel structural and a 21channel site arra...

in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

concrete filled steel tube columns (cfst) are a kind of composite columns according to advantages of cfst relative to reinforced concrete and steel columns. use of these materials is common in recent years especially in high building, unnecessary of molding, high ductility, proportionate resistance with low volume, economical, low deformation relative to steel columns are among advantages. in t...

Abstract Recently, the reinforced cement concrete (RCC) frame has been one of most commonly used structural systems for buildings in high seismic region due to its inherent earthquake-resistant property. However, there is still a deficiency understanding RCC building system dynamic behaviour during significant earthquakes. A 1/4th scaled framed structure tested on shake table present study. The...

This work investigates and discusses the effectiveness of seesaw system when installed in an older, non-ductile reinforced concrete (RC) building for seismic upgrading purposes. In particular, two different configurations are assumed a two-storey 3D RC framed which was designed according to older provisions and, thus, is susceptible flexural shear failures. To check if there any merit employing...
