27. Paul Stewart4/12/2010Structural Option PRESENTATION OUTLINE Introduction Existing Structural System Proposal Design of Helipad Breadth Study Redesign of Lateral System Conclusion CONCLUSIONS Helipad will be located in Zone 5 The Pad will be designed as a two – way slab New columns will be introduced along column line Ma The façade of the building will be changed Lateral system will eliminate of moment frames Braced frames will not interfere with the architecture Drift values will be larger, but still acceptable Differences in COM and COR are generally the same
