Abstract
Reinforced concrete has been shown to be a desirable material of choice in blast resistant structures due to its availability, relatively low cost, and its inherent ability to absorb energy produced by explosions. Most research work investigating the behaviour of reinforced concrete columns to blast loading have concentrated on their response to planar loading from far-field explosions. Limited amount of work is available on the effects of near-field explosion on the behaviour of reinforced concrete columns. This study is aimed to investigate effects of explosive loads on RC column by using ALE method. Commercial finite element package, LS-DYNA is used to simulate the behavior of blast wave on RC columns. Numerical simulation is validated against experimental work done in literature. The experience gained from this research provides valuable information for the development of the finite element modeling of real blast load effects on RC columns.
Highlights
Explosion effects on structures have been an area of research over the last decades [1]
Due to the uncertainty and difficulty in predicting accidental explosions, little information is available on the design guidelines and performance of reinforced concrete structures subjected to blast loading [5]
The main objective of the current study is to evaluate shock wave interactions with reinforced concrete columns using arbitary lagrangian eulerian method
Summary
Explosion effects on structures have been an area of research over the last decades [1]. Many research works have been published in the literature studying the effects of blast loading on reinforced concrete elements [2,3,4]. Due to the uncertainty and difficulty in predicting accidental explosions, little information is available on the design guidelines and performance of reinforced concrete structures subjected to blast loading [5]. Semi-empirical methods are based on simplified models of physical phenomena. The attempt is to model the underlying important physical processes in a simplified way These methods are dependent on extensive data and case study. Numerical methods are based on mathematical equations that describe the basic laws of physics governing a problem. These principles include conservation of mass, momentum, and energy.
