Overview:

Studio Gang’s unique design approach is predicated on interdisciplinary collaboration with expert partners ranging from engineers and ecologists to artists and journalists. In this lecture, Jeanne will discuss how this deep and sustained engagement across fields has resulted in the material, spatial, and aesthetic innovations that define award-winning projects like the supertall St. Regis Chicago tower, the city’s third tallest building, and the Arcus Center for Social Justice Leadership, which unites traditional cordwood masonry practices with contemporary design and building technologies.

Performance-based Seismic Design of Tall Buildings

Overview:

Performance-based seismic design of tall buildings in the western United States began in earnest shortly after the turn of the 21st century. Although even the first designs were subject to independent peer review, there were no guidelines or accepted criteria for how to conduct and review a performance-based design, with the result that similar buildings were often designed to satisfy distinctly different criteria. Guidelines and building code provisions were soon developed to improve uniformity in design approaches and to foster the adoption of the performance-based approach. This lecture will review the development of performance-based seismic design of tall buildings, document a typical design application, and summarize results of over a decade of experience in tall building designs.

Understanding the Seismic Performance of Structural Systems through Lare-scale Experiments and Computational Simulations

Overview:

The development of design standards for seismic force resisting systems has been relying on data from numerical simulations and laboratory experiments for a long period of time. However, these simulations have often been performed with highly simplified computational models either because of their computational efficiency or because of the lack of more refined modeling options. Moreover, most experimental studies focused on isolated structural elements or subassemblages, which were typically tested to a state of severe damage but not to the point of incipient collapse. It is well recognized that the performance of a structural system in an earthquake depends on how the structural elements interact, which dictates the resulting inelastic mechanisms, as well as on the alternate load paths and redundancy provided in the system. To compensate for the lack of system response data for model validation, design specifications and evaluation criteria often have to have added conservatism. This may not only result in less economical systems but also a lack of uniform safety level across structural materials and systems. To develop reliable performance-based seismic design guidelines, accurate and efficient computational models are essential for predicting the damage states as well as accessing the possibility of collapse of a structural system in an earthquake. Computational modeling of the response of reinforced concrete and masonry structures for such purpose is especially challenging as these structures can develop complex inelastic mechanisms, including the cracking and crushing of concrete/masonry, the yielding, buckling, and fracture of reinforcing bars, and the interaction between the two materials. This lecture demonstrates the importance of structural system testing and refined computational modeling to the advancement of design standards for reinforced masonry structures, and presents some recent work along this direction including major findings.
