Earthquakes cause a lot of damage to structures. A quantitative estimate the amount structure always seems quite necessary after an earthquake. For this purpose, seismic indices have been introduced as dimensionless quantities that can report extent using various criteria. This assessment help make decisions about process improving, repairing, and strengthening paper presented new stiffness-bas...

Abstract The approach for seismic strengthening of RC frames using moment redistribution and externally bonded FRP is especially applicable enhancing the performance a building that designed prior to introduction new codes. design detailing requirements these categories were conducted following capacity principle. Based on more recent codes, buildings are under-designed, has become mandatory. A...

This paper investigates the effect of span cantilevered RC wall, in-plane stiffness roof, layout friction damper support on both response control walls in gymnasiums with metal spatial roofs and proposed evaluation method. According to history analysis results, method was proved be available various formula column base moment modified following appropriate diagram.

Researchers awarded a considerable attention to progressive collapse analysis in recent years avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established base deal with such catastrophic failure. For multi-story building, these proposed column removal scenario which one more columns different locations should be removed from structure. Then, re...

Strengthening of concrete structures is applied as a solution for various deterioration problems in civil engineering practice. This paper presents an analytical study the behaviour cross-section reinforced (RC) beam, strengthened flexure with fiber polymer (FRP) materials. Using balance internal forces cross section through all phases stress which passes, program was written MATLsoftware, exec...
