“…This is because concrete has been widely used in earthquake, impact and blast environments where the dynamic tensile strength plays an important role. The previous researches (Brara and Klepaczko, 2006;Li et al, 2009) showed that the tensile strength appears to increase with strain rate, _ å, when the rate is above a critical value of around 10 0 ,10 1 /s. This paper investigates the dynamic tensile strength of steel fibre reinforced concrete through the SHPB spalling tests.…”

The dynamic tensile strength of steel fibre reinforced concrete is experimentally investigated. Cylindrical specimens are first fabricated with three different fibre volume fractions of 0, 0 . 75% and 1 . 5%. These specimens are then tested by using the Hopkinson pressure bar technique. Their dynamic tensile strengths are measured under medium strain rate impact. In these tests, the stress histories are recorded by way of the strain gauges symmetrically mounted on the specimen and the post-test fracture modes are photographed. The test results indicate that the superposition of waves induces first compressive stress and then tensile stress. Once the tensile stress reaches its critical value, a spalling phenomenon occurs. Both volume fraction of fibres and strain rate exert a significant influence on the dynamic tensile strength of concrete. Furthermore, the strain-rate-induced enhancement of tensile strength is related to the compressive strength of the concrete matrix.

“…Clubley [11] performed full-scale tests and FE simulations to investigate response of cylindrical shell structures subject to high power long-duration blasts from sources such as hydrocarbon vapor cloud. Li et al [12] investigated the dynamic responses of reinforced concrete frame structures when subjected to distant blast loadings caused by explosions. It was found that the effect on cladding panels were more severe due to the variations of blast forces acting on the structure.…”

“…Another study on concrete buildings also indicates that a more realistic assessment about the impact of explosion on structures can be achieved when the analytical model of a building is updated on the basis of Operational Modal Analysis (OMA) results and when the dynamic analysis is carried out for the blast record [4]. Other recent studies examine the impact of ground motions caused by the shock of the explosion and its comparison with the effects of earthquakes on rigid building blocks, the effect of shear wall on RC buildings retaining turbines in the nuclear industry, and the exact simplification of the time history of blast pressure; and other study have developed a method to calculate the annual collapse risk in strategic buildings [5][6][7][8].…”

Surface explosions resulting from terrorist attacks will produce a hemispherical shock wave in the air, which, upon release, can affect five faces of the building which is in front of it. Given the fact that conventional buildings are usually exposed to such explosions, this study examined the effect of pressure to each face of a building on the responses of the structure and has compared different relevant scenarios. This study, which includes the following two steps, was conducted as a case study on earthquake resistant RC buildings, with the help of UFC guideline and using the software SAP2000. In the first step, responses of loading on each face were separately calculated so that they were compared with the responses from overall loading on all faces. The sensitivity of the responses and their ratio to the variables considered were evaluated in the second step. Accordingly, an outline was formed on the explosion hazards considered for these types of buildings.
