Abstraksi:The actual dynamic response of tall buildings on soft soil against earthquake loading is a very complicated one. The desire to have in-elastic responses of the superstructure's structural elements while maintaining the response of the underground structural system remain elastic is not easy to model even with the current advances achieved in available non-linear dynamic structural analysis commercial software. Thus, in this study a parametric study of dynamic behavior of tall structural tower on soft soil are presented which used four type of soft soils configuration representing the condition in Jakarta and Surabaya. The soil structure interaction option using elastic vertical and lateral spring constants were utilized to account for the dynamic contribution of the soft soils on the lateral resistant of the deep foundation system. The result were used to derive the indication on what should be the problem encountered. The conclusion were then used to formed necessary basic concept on the design of earthquake-resistant of tall building with basement and deep foundation on soft soil. The use of available Non-Linear Soil-Structure Interaction Software should be tempered with caution. At best the result will only give indication on the actual behavior of the structure and depend heavily on the accuracy of the non-linear characteristic of the material and elements considered and assumed for the analysis. While the result shows that ground fixity level provide conservative result for the superstructure, the reverse is true for the deep piling foundation system. Large lateral deformation of the foundation system were observed indicating the possible significant reduction to the actual load carrying capacity of the piles. Mass dan rigidity of the basement seems to play an important part of the load transfer capability of the whole structure and hence should be carefully review together with the architects.
