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...

This paper presents the findings of an experimental investigation on a reinforced concrete frame structure (ordinary moment resistant frame). The test model was subjected to lateral excitation employing 1994 Northridge earthquake accelerogram. fabricated in 1:3 reduced scale acquiring dimensional similarities. utilized ingredient mix ratio 1:1.65:1.75 and water binder 0.47. dynamic characterist...

This article examines the baseline resilience of reinforced concrete (RC) moment frame buildings conforming to seismic design standards Canada. Metrics for robustness, rapidity, and are evaluated capture system’s reliability, speed recovery, socioeconomic impacts. Buildings different heights using nonlinear time-history analyses. Six damage states defined as disjoint branches an event tree depe...

Stress-strain and moment-curvature behavior of the reinforced concrete (RC) square columns have been analytically investigated according to different confined models. The effect transverse reinforcement diameter, spacing grade on RC column models were investigated. For models, confinement effectiveness coefficient, effective lateral confining stress, compressive strength, strain at maximum stre...

In determining the seismic performance of reinforced concrete (RC) structures in national and international earthquake regulations, it is desired to use effective section stiffness cracked RC structural elements during design phase. Although not constant, depends on parameters such as strength reinforcement ratio. this study, beam models with different strength, tensile compression ratios were ...

Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...

BACKGROUND Global resurgence of dengue virus infections in many of the tropical and subtropical countries is a major concern. Therefore, there is an urgent need for the development of successful drugs that are both economical and offer a long-lasting protection. The viral NS2B-NS3 serine protease (NS2B-NS3pro) is a promising target for the development of drug-like inhibitors, which are not avai...
