This paper presents the difference in behavior between hollow-core fiber reinforced polymer-concrete-steel (HC-FCS) columns and conventional reinforced concrete (RC) columns under vehicle collision in terms of dynamic and static forces. The HC-FCS column consisted of an outer FRP tube, an inner steel tube, and a concrete shell sandwiched between the two tubes. The steel tube was hollow inside a...

This paper presents the results of an experimental campaign performed at the Laboratory of Materials and Structural Testing of the University of Salerno (Italy) in order to investigate the seismic performance of reinforced concrete (RC) beam-column joints strengthened with steel reinforced polymer (SRP) systems. With the aim to represent typical façade frames’ beam-column subassemblies found in...

A beam-column element based on the Euler-Bernoulli beam theory is researched for nonlinear dynamic analysis of reinforced concrete (RC) structural element. Stiffness matrix of this element is obtained by using rigidity method. A solution technique that included nonlinear dynamic substructure procedure is developed for dynamic analyses of RC frames. A predicted-corrected form of the Bossak-α met...

This paper is concerned with determining the minimum stand-off distance required to prevent column failures in reinforced concrete framed buildings. This is of interest because column failures can initiate progressive collapse, resulting in mass casualties. A technique is developed to determine the critical range at which failure will occur for a given weight of explosives and thus provide a sa...

To serve its purpose a structure must be safe against collapse and serviceable in use. Serviceability requires that deflections be adequately small to keep the cracks within tolerable limits. Although the widely followed ACI Code suggests a detailed method of deflection calculation, it often cannot exactly perceive the actual behavior of a structure. For this purpose, finite element analysis, u...

The response of moment resisting frame structures to seismic excitation is strongly dependent on the ability of particular structural members to sustain relatively large inelastic deformations without significant degradation of lateral and axial load-carrying capacity. Conventional reinforced concrete frame structures are typically designed according to the strong column/weak beam concept, whic...
