The following two analytical problems for supporting the construction planning of structures by using computers are studied: (1) Analysis of initial shape before construction An analysis of initial shape before construction with estimating construction process is proposed in this paper. An example of truss structures is analyzed. (2) Inverse analysis for construction process by removing members An inverse analysis for construction process by removing members is proposed in order to find an optimum solution of the construction process satisfying given criteria. The analysis searches for a construction process satisfying given criteria by removing members in order from a finished structure. Examples of truss structures are analyzed.
