This research, concrete materials used SHCC(Strain harding Cementitious Composite) in RC(Reinforced Concrete) shear walls. We tried to identify the performance of developed shear wall. Specimens were only considered gravity load and designed and detailed in compliance to KCI-2012. Based on the loading experiment results, this study was found that the developed shear walls showed improved strength than RC shear wall in controlling bending and shear crack. The developed　shear wall with minimum shear reinforcement increased the more strength than RC wall with nominal shear reinforcement

In order to apply a mechanical deck joint to the prefabricated steel gird composite decks, shear resistance of a joint composed of concrete shear key and high-tension bolt is experimentally evaluated by the push-out test. In comparison with resistances estimated by empirical and design equations, the deck joint can be safely designed. But because the existed shear resistance of deck joint is underestimated by the ACI-318, application of the LRFD design equation could be more reasonable.
