<br/><br/> Investigation of mechanical behavior of embedded box-type reinforced concrete structures,  concerning shear rigidity and its reduction, has been done analytically in this study by using a  finite element program for a non linear analysis of reinforced concrete plate element called  WCOMR.  From the parametric study, it was found that lower reduced shear rigidity factor, which  was defined as the ratio of reduced and initial shear rigidity, could be attained by an-anging  thinner RC duct wall thickness, lower concrete compressive strength, higher yield strength of  reinforcement, higher reinforcement ratio, and smaller embedment depth.  In order to be able to predict the reduced shear rigidity factor, a fo1mula has been derived  by considering the effects of various parameters.
