1 2 3 4 A H H B H H H ATRIUM D H E H 8 H F H You are provided a concept layout for a building's typical floor plan by an Architect, as shown above. The architect has proposed a concrete service core to southern edge of the floor plan, which is partially enveloped by a large floor opening which serves as an open atrium throughout the height of the building. The architect suggests that you can use the concrete core as a shear wall system. Write a discussion on how you would advise the architect on the following. a) If the core is to be used a shear wall, please advise the architect on the suitability of its location relative to the center of mass of the floor, and its connectivity to the floor diaphragm. Explain how these are likely to influence the behavior and performance of the building's lateral system. [15 marks] b) Assuming that you are permitted to add additional shear walls provide an annotated sketch of the structural alterations to the lateral system that you would recommend. Write a brief explanation for your recommendations. [5 marks] c) Assuming that you are NOT permitted to add additional shear walls or braces provide an annotated sketch of the structural alterations that you would make to the lateral system. Write a brief explanation for your recommendations. [5 marks]
