Highrise buildings having structural irregularities could be much susceptible to earthquake damage due to torsional response. For the optimal seismic design and retrofit of such structures against earthquake loads, many iterations of structural analysis and design change are often needed. To ensure a closed loop of assessment and adjustment in the design process, this study proposes an integrated seismic assessment and design framework. Revit Structure from Autodesk, one of the Building Informational Modeling (BIM) software, and ZEUS-NL from Mid-America Earthquake (MAE) Center, one of the advanced earthquake simulations programs, are utilized for structural design and analysis tools. Then, a robust bi-directional link interface coupling two different programs is developed which can transfer required data in both directions without any loss of information. Also, this tool provides advanced seismic assessment and design guidelines that address damaging torsional effects. Through the application example, the feasibility of the proposed framework and its components are successfully evaluated and verified. Upon the proposed framework more reliable and better seismic designs especially for irregular highrise buildings can be pursued.
