System-level advanced analysis is now a viable tool for widespread use in structural design. By directly capturing frame and member level instability effects, plasticity, initial geometric imperfections residual stresses the analysis, need subsequent individual checks can be eliminated. The of members frames typically carried out using beam elements, which are unable to capture effects local bu...

The use of composite materials for strengthening the ailing infrastructure has steadily gained acceptance and market share. Employing composite materials in strengthening of steel structures is the subject of this study. There are several challenges that face strengthening steel structures using composite materials. The superior mechanical properties of steel result in a reduction in the effici...

This paper presents an analytical model to estimate the cost of an optimized design of reinforced concrete isolated footing base on structural safety. Flexural and optimized formulas for square and rectangular footingare derived base on ACI building code of design, material cost and optimization. The optimization constraints consist of upper and lower limits of depth and area of steel. Footing ...

This paper reports the findings of research examining the blast resistance of bridge piers that are designed in accordance with current knowledge and specifications to ensure ductile seismic performance. Blast testing was conducted on 1/4 scale ductile RC columns, and nonductile RC columns retrofitted with steel jacketing. The seismically designed RC and steel jacketed RC columns did not exhibi...

The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...

In this study, 11 PSRPC column specimens were designed and fabricated in order to investigate the stressing performance of incompletely prefabricated steel reactive powder concrete (PSRPC) columns subjected static loading tests. The effects strength grade content (RPC) on axial compression eccentricity investigated. test results show that external RPC, internal section cast-in-place RPC work we...
