Analysis and Design of Double-Beam Coupling Beams

Author(s) Youngjae Choi and Shih-Ho Chao   Abstract Double-beam coupling beams (DBCBs) are a viable alternative to diagonally reinforced concrete coupling beams (DCBs). While construction time and effort of DBCBs is much less than DCBs, their ability to sustain...

Behavior of Foamed Concrete Slabs Using Various Reinforcement Schemes

Author(s) Rabab Allouzi   Abstract Foamed concrete exhibits enhanced mechanical, thermal and acoustic characteristics. Such properties seem to be a suitable alternative to fit evolving properties required in the housing industry. The main challenge is to select a...

Splice Strength of Reinforcing Bars with High and Low Alternating Ribs

Author(s) Oan Chul Choi, Seung Yul Yang, and Hajin Choi   Abstract This paper describes an experimental analysis of 41 beam specimens conducted to investigate the splice strength of reinforcing bars in a novel alternating high and low rib pattern. The newly...

Experimental Study of Direct Shear in Concrete with Recycled Aggregate

Author(s) Juliana Trindade, Sergio Garcia, and Gabriel Fonseca   Abstract To investigate shear transfer in recycled and natural coarse aggregate concrete, 45 pushoff specimens were tested. Replacement levels of natural coarse aggregates by recycled aggregates in...
