Abstract: An analytical model to predict the behavior of concrete confined with fiber reinforced plastic (FRP) composites subjected to axial compressive loads was developed. First, a constitutive model for plain concrete was formulated ...

Abstract: This paper examines the impact responses of reinforced concrete (RC) beams through an experimental study and presents an analytical model developed to predict the maximum midspan deflection and maximum impact load, which ...

Abstract: This research studied the feasibility of crumb rubber mortar (CRM) as a novel shock-absorbing material for protecting structures from blast and impact loading. Waste tire–derived crumb rubber was used in combination with ...

Abstract: Ryukyu limestone, which is distributed widely in the Ryukyu Islands, Japan, may be unsuitable for use as coarse aggregates for concrete because of its high water absorption rate and low strength. This study experimentally ...

Abstract: With the aim of developing cast-in-place geopolymer mortar hardened under ambient temperature, this study investigated the effects of the composition ratio of fly ash (FA) and ground granulated blast furnace slag (GGBFS) ...

Abstract: The collapse of structures due to massive seismic events is usually observed around the world. It is very important to rescue people who are trapped inside the collapsed RC structures by a big earthquake within 72 h after ...
