Abstract: A proper traction–separation law based on the physical behaviors of the concrete–epoxy interface is needed to simulate the debonding behavior of fiber-reinforced polymers–strengthened concrete structures. However, no method ...

Abstract: A viable alternative to reinforced concrete coupling beams with heavily reinforced diagonal struts is steel or steel-concrete composite beams. A limited number of previous studies have examined various issues related to ...

Abstract: As shown in a companion paper, the embedment length of steel-concrete composite coupling beams inside wall piers should be computed by incorporating the contribution of the encasement. In lieu of detailed fiber-based ...

Abstract: A 45-year old, three-span reinforced concrete slab bridge with insufficient capacity was retrofitted with 76.2- and 127-mm wide bonded carbon fiber-reinforced polymer (FRP) plates, 102-mm wide bonded carbon FRP plates with ...

Abstract: A wide range of experimental data and associated analytical results are used to examine the applicability of two widely used design codes (i.e., ACI and AISC) for calculating the capacity of concrete-filled steel tubular ...

Abstract: Experimental results from a series of earthquake simulations on a one‐quarter scale model of a moment‐resisting reinforced concrete frame are presented. Using the test results, some of the U.S. seismic design provisions ...

Abstract: A simple model to account for the contribution of slabs to the strength and stiffness of beams under negative bending at a beamcolumn connection is proposed. In the model, the slab is assumed to act as a tensile membrane ...

Abstract: Contribution of monolithic floor slabs to the negative (hogging) flexural resistance of beams in reinforced concrete frames may inadvertently affect the hierarchy of failure unless it is considered during the design. A ...

Abstract: The cyclic response of steel coupling beams embedded into reinforced concrete boundary elements was studied. Three half‐scale subassemblies representing a portion of a prototype structure were designed, constructed, and ...

Abstract: When coupled core wall (CCW) systems are built in regions of high seismicity, the ductility demands on the coupling beams can be of critical concern. Steel coupling beams, whether encased in concrete or not, offer a very ...
