| Abstract: |
Due its height and expressive architectural design the (W)rapper Tower is set to become a landmark building in Los Angeles, CA. The structure is architecturally driven and features exterior curved steel boxes “Bands”, an eccentric Steel Plate Shear Wall (SPSW) core and Seismic Base Isolation. Performance Base Design (PBD) using LATBSDC guidance was adopted for the design and the performance of the Tower. The structure was assessed using Non-Linear Time History Analysis (NLTHA) in LS-Dyna with 63 earthquake simulations (nine suites of seven ground motions each). The analysis and post-processing used an automated workflow relying on cloud computing and custom database post-processing. This paper describes the development of the structural system and the analysis process employing numerous advanced modelling and visualization techniques. |
