The Continuous Strength Method (CSM) is a deformation based design approach that provides accurate cross-section resistance predictions by making rational allowance for the interaction between elements, partial spread of plasticity and beneficial effects strain hardening. CSM can be used in conjunction with advanced analysis members frames, but, hand calculations, member-level stability checks ...

The optimisation of the design method for verification slender steel beam-columns is still a current issue not only from scientific point view, but also practice. Therefore, main objective this paper comparison suitability established approaches, according to European standards and aluminium structures, on basis numerical simulations. Thus, finite element model was validated experimental analys...

buckling instability is the most important factor at columns failune. icauses large deflection and mostly is analysed by first yield criterion. due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. in this research project a number box- secti...

Since laboratory tests are usually costly, simulating methods using computers always under the spotlight. This study performed a finite element analysis (FEA) iterative solutions for circular and square concrete-filled steel tube (CFST) columns infilled with high-strength concrete reinforced cross-shaped plate (comprising two plates along that divide hollow into four equal sections) without ope...

Glass fiber-reinforced polymer (GFRP) reinforcements are useful alternatives to traditional steel bars in concrete structures, particularly vertical structural elements such as columns, they less prone corrosion, and impart increasing strength endurance of buildings. There is limited research on the finite element analysis (FEA) behavior hollow glass reinforced (GFRPRC) columns. The portion can...

Reinforcement grades higher than 75 ksi (520 MPa) are not allowed in members that form plastic hinges due to a lack of information on material characteristics and on the seismic performance of columns constructed with high-strength steel (HSS) reinforcement. This research investigated the performance of reinforced concrete columns containing Grade 80 (minimum yield strength of 80 ksi [550 MPa])...

To investigate the bearing capacity of hollow Glass Fiber Reinforced Polymer (GFRP) pipe-concrete-steel tube composite long columns subjected to eccentrical compression load, 33 GFRP have been designed. The slenderness ratio (?), compressive strength concrete cube ( f cu ), eccentricity (e) and so on are main parameters. Based constitutive models for steel, confined concrete, numerical simulati...

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...
