Abstract

This study suggests the simplified construction sequence analysis scheme which predicts the lateral displacements of reinforced concrete structures under construction, with basic design and construction information in structural design stages. In each construction stage, elastic vertical and lateral displacements due to vertical loads are calculated by using stiffness matrix of the structure, and the inelastic shortening of vertical members due to creep and shrinkage are added. Also, lateral displacements caused by the differential shortening of vertical members are calculated by the equivalent loads from compatibilities of vertical displacements. Total lateral displacement is calculated by a summation of elastic lateral displacements of the structure, horizontal components of the inelastic shortening of vertical members, additional lateral displacements caused by the differential shortening of vertical members, and lateral displacements caused by shrinkage of horizontal members. The the proposed method is verified by applications to a regular-shaped building under symmetric load or asymmetric load, and a complex-shaped building with zoning construction.
