This study presents experimental and numerical investigations on seven one-way, reinforced concrete (RC) slabs with a new technique of slab weight reduction using polystyrene-embedded arched blocks (PEABs). All had the same dimensions, steel reinforcement, compressive strength. One these was solid slab, which taken as control while other six were cast PEABs. The main variables ratio length PEAB...

seismic retrofit of masonry slabs in existing steel or masonry buildings has found special significance in current codes as failure of unstable jack arch slabs has been reported as a major reason for collapsing structures in middle east deadly earthquakes. in this paper, three retrofit schemes are investigated and compared. the proposed rehabilitation techniques consist of a single x strapping,...

Abstract Concrete is a brittle material that weak in tension and prone to internal microcracking. With the constant demand for improvement concrete’s durability mechanical proprieties, use of fiber reinforcements has shown promising results. The findings this paper are based on test results hybrid reinforced concrete (HFRC) samples simply supported two-way slabs, produced with selected volumetr...

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...

This study investigates the deterioration process and mechanism of reinforced concrete (RC) slabs in road bridges under dry stagnant water (wet) conditions. Previous studies used a simple-plate model (SPM) to predict fatigue life RC decks by considering conservative assumptions for safer assessment different environmental processes. To obtain more detailed analysis clarify result mechanism, ful...
