Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

Estimating safe scaled distances for columns subjected to blast

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...

Numerical Simulation of FRP-Jacketed RC Columns Subjected to Cyclic Loading

This paper presents a study that forms part of an ongoing project on the seismic retrofit of reinforced concrete (RC) structures with fibre-reinforced polymer (FRP). In this study, a stress-strain model for FRP-confined concrete subjected to cyclic loading was implemented into OpenSees to support the performance-based design of FRP jackets for the seismic retrofit of RC columns/structures. Init...

Finite Element Analysis for CFST Columns under Blast Loading

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

Numerical Simulation of an Armored Vehicle Underbelly Subjected to Air Blast Loading

In modern warfare, anti-vehicular mine attack is one of the critical consideration in the design of an armored personnel vehicle. Nowadays, the use of computational tools is a common approach in vehicle design process for evaluating the vehicle and its occupant’s safety or protective levels. This paper presents a finite element analysis carried out on the underbelly of SIBMAS AFSV 6x6 armored v...
