We have many difficulties in the modelling and load transfer mechanism analysis of stone pagoda structure because it is regarded as masonry system. So, this study evaluates the vertical load transfer mechanism through the structural modelling and analysis considering the discontinuum behavior and contact surface mechanism for the three-story stone pagoda in Goseon-sa temple site. To this end, this study considers the discrete element method for the discontinuum modelling and analysis of masonry structure. Also, the vertical load transfer mechanism is evaluated through the comparison of the analysis results.

Because the stone pagoda structure is considered as the discontinuum masonry system, many difficulties are given in the modelling and analysis process. Therefore, this study investigates the construction types of stylobate for the three-story stone pagoda in Goseon-sa temple site. Also, this study evaluates the vertical load transfer mechanism through the structural modelling and analysis by the discrete element analysis and finite element analysis with the consideration of the discontinuum behavior and contact surface mechanism. To this end, the internal jeoksim types of stylobate are considered in the analysis process. Also, the efficiency of load distribution method for checking the vertical load transfer of each element is analyzed through the comparison of analysis results.

This study presents the initial shape design of steel truss structure using topology optimization. Traditionally, the structural design process starts with an initial conceptual model which is inspired by the designer’s intuition and previous experiences. But traditional procedure is too slow and inefficiency. Therefore, this study presents a necessary method in the development of initial shape design of steel truss structure. Also, this study is expected to contribute to effective layout of structures and designer's design.

Single latticed dome has many types and each has a different shape decision theory. Therefore, the big difference in the total weight and the behavior of structures is shown, depending on the selection of some single latticed dome. Also, the initial design of single latticed dome depends on the structural engineer's experience and the repeated trial end error. For this reason, it is not easy to optimize the economic size and height in the design of this system. Therefore, this study presents the shape decision scheme of each selected single latticed dome and development of optimum design algorithm for the optimal shape decision in the initial design. First, the automated computation of joint coordinates and automatic input of the load are considered for the shape modeling of geodesic dome, parallel lamella dome and schwedler dome. Also, the optimal design formulation and algorithm are presented through the sensitivity analysis technique and the various example models are applied.
