The present study proposes a new method to predict the ultimate load bearing capacity of structural notched beams subjected splitting. Reinforced and unreinforced cases are investigated by using FE-model for splitting failure. contribution mode I II in crack extension mechanisms is implemented numerical model considering mixed criterion established on R-curves wood. influences notch reinforceme...

this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...

This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A ...

High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...

Abstract The number of bridges approaching or exceeding their initial design life has been increasing dramatically. Meanwhile, are withstanding an ever-increasing traffic volume, both in and weight vehicles. Analytical numerical models can predict bridges’ response to loads ultimate capacity with low uncertainties; however, such uncertainties increase as age due deterioration mechanisms. Non-de...

composite concrete-steel plate shear walls are the most critical resisting structural members that resist lateral and axial loads. This type of wall consisting of two steel faceplates presenting the outer skin, infill concrete and shear connectors which are used to provide the composite action of the steel faceplates with infill concrete in order to increase the strength and to reduce the local...

The present study aims to investigate the effects of steel fibers (SF) and polypropylene (PPF) on structural response one-way simply supported reinforced concrete (RC) slabs at ultimate limit state (ULS). Next, an optimized combination hybrid is proposed. experimental program includes 21 experiments with different SF PPF ratios. load-deflection curves were obtained for using a four-point bendin...

16. Abstract Four scale microconcrete model bridges were tested. Experimental variables included span, skew angle, stiffness, location and number of diaphragms. Service load level behavior was studied under static, cyclic and impact loads with successive removal of diaphragms. Behavior at overload and ultimate load conditions was documented from ultimate static and impact load tests. Characteri...
