THE APPLICATION of STM (BASED on ACI 318-02) and FEA for THE DESIGN of STRUCTURAL TRANSFER-WALL
Dissimilar room functions in the mixed-use building can cause the unaligned column gridline from the lowest floor to the top floor. The transfer loading from one column to two columns or vice versa sometimes is unavoidable in architectural design. The reaction force should be transferred from the column is enormous and requires special structure such as transfer-wall or deep-beam. The value of deep-to-span ratio of transfer-wall is not satisfying the flexural-beam criteria so it needs a special design, base on the deep-beam requirement. The detail design of deep beam has not yet incorporated in SNI 03-2847-2002 therefore Strut-and-Tie Model (STM) method from ACI 318-02 Appendix A will be applied. This method was formalized from the research in University of Stuttgart, Germany, by Schlaich et. al. in 1987, since then growing extensively (Adebar et. al. 1990; Jirsa et. al. 1991; K.H. Reineck 1996, 1999, 2002), and now has been adopted by several design standards in Canada, USA, and New Zealand. This paper will provide the application of STM based on ACI 318-02 for the design of transfer-wall in the “Kota Kasablanka” Mixed Use Project, Jakarta. Finally, the result of the design will be evaluated by Finite Element Analysis (FEA) program in order to make a strength comparison.
