Abstract

This paper presents design procedures for 1-D and 2-D strain hardening cement composites (SHCC) members based on analytical models. Closed-form solutions of moment-curvature responses of SHCC are derived based on elastic perfectly plastic compressive model and trilinear strain hardening tension model. Tension stiffening behavior of SHCC due to fiber toughening and distributed cracking are considered and incorporated in the cross-sectional analysis. Load-deflection responses for beam and panel members are obtained using several different methods including moment-area, direct integration and Yield Line Theory. The proposed models provide insights in the design of SHCC to utilize the hardening properties after cracking. Using proper parameters, generalized materials model are applicable to both SHCC and strain softening cement composites such as steel fiber reinforced concrete (SFRC), textile reinforced concrete (TRC) and ultra-high performance concrete (UHPC).
