“…Response of an individual column to rock impact Past investigations of the response of structural elements to impacts show the complexity of the phenomenon, with the final effect depending on the interaction between the impacting body and the structure associated with relative masses, velocities, the contact zone, stiffness, frequency of loading, and geometry of the impact (Remennikov and Kaewunruen 2006;Kishi et al 2002Kishi et al , 2007. A detailed presentation of the phenomenon of direct impact on reinforced concrete structures, including information on the development of impact forces, is presented in Delhomme (2005).…”

A procedure is presented for investigating the response of reinforced concrete buildings to rockfall impact. The method considers a single rock hit on the basement columns, and it includes four steps: (a) calculation of the probability of a rock impact on a member of the load-bearing system, taking into account the block size and the design of the structure; (b) evaluation of the response of one or more structural elements to the hit based on element capacity; (c) in the case of structural element failure, assessment of the robustness of the whole structural system, calculating the potential for progressive collapse; and (d) calculation of a damage index (DI), which is the ratio of structural elements that fail to the total number of structural elements. The proposed method is applied to a reinforced concrete building for a range of rockfall paths and intensities. The analysis has been carried out for a 2-m-diameter block and velocities< 3.5 m/s. The possible damage range is found to be highly variable, with DI values ranging from 0.01 to 1 depending on the impact location and block velocity.

“…There are many factors affecting the behavior of RC members under impact loading such as the dimensions and span of members, cross-section properties (steel ratio, stirrups, concrete cover), material properties (concrete, steel, FRP) and stiffness of the impact surface, (Bhatti et al 2009(Bhatti et al , 2011Fujikake et al 2009;Ho 2004;Kishi and Mikami 2002;Kishi et al 2002Kishi et al , 2006Saatci and Vecchio 2009;Remennikov and Kaewunruen 2006). The only testing parameter in this experimental study was the strengthening effect.…”

Structures can be exposed to impact loads as a result of an explosion, falling objects, projectiles and vehicle collisions. Within the increasing threat of these impact sources, it is very important to protect the columns that are the vital members of the structural systems to ensure structural and personal safety. This study focuses on the performance of axially loaded reinforced concrete members subjected to impact loading. A dropped-weight test set-up developed to perform impact tests on reinforced concrete members. The test set-up was used to perform low elevation impact tests on reinforced concrete (RC) columns that targets to simulate vehicular impact against ground floor columns of low-rise buildings. Since, there is limited information about the transverse impact performances of RC columns; the main objective of this research is to assess the vulnerability of RC columns under transverse impact loads and to enhance their performances by using Aramid Fiber Reinforced Polymer (AFRP) sheets. The scope is limited to 300 mm square columns with 3 m height in low to medium rise buildings which were found to be more vulnerable to lateral impacts according to previous research conducted by the authors, (Gurbuz et al. 2010(Gurbuz et al. , 2011. This research provides fundamental knowledge on the behavior of RC columns under low elevation impact loading and also generates new information on impact strengthening of vulnerable concrete columns by AFRP sheets.

“…The majority of the finite element packages commonly used in practice for the impact analysis of RC structures, however, require undertaking sophisticated solutions of a contact problem between two colliding objects modeled with high detail. 4,5 Although such an approach removes the limitations on the geometry of the structure and allows the analysis of a wide range of impact load cases, it also creates major disadvantages for practical design purposes when the complexity of the modeling and the length of computation time are considered. Moreover, modeling the behavior of RC has always proven to be challenging in many aspects.…”
