Good Morning Everyone

Good morning everyone, we are group number 4. My name is Feng, and here are our design team members, Josh, Jeremy, Dan, and Allan. Today we are going to be presenting our design building, which is located in Vancouver, British Columbia. Here is the overview of our design building; it has 25 residential floors, 5 garage floor at the bottom. And on top of it, it includes health club, gymnasium, as well as outdoor Rooftop pools and helipad. The design concepts and skills we basically used are followed by NBCC and Concrete Design Handbook 2005. Our structure was built to provide structural integrity, workability alongside architect, and economic design. We spilt the design into 5 components, and on the right side of the slide, is our design team Philosophy. To start off, our design was based on some assumptions which were later checked with SAP 2000 Program. We used 30 MPa concrete, 400Mpa steel, M10 bars throughout the whole slab structure with modifications over some critical sections. In order to begin the analysis of this complex load resisting system, each design steps were structurally related and couldn’t be done without enough communications between us throughout the whole design process. Our design is cyclical and here is a list of our design steps. In terms of building structural system, our structure was designed to resist gravity and lateral loads. For gravity load, we used flat slab system with columns, and addition of columns at some critical parts to make flat slab more economical. Josh is going to talk about the slab in more detail later. For lateral loads, cores and shear walls were used. Also, due to the size, height and seismic zone, many shear walls were incorporated to reduce the cross-sections/cost.
