PDD Case Study - Resources

Resource 1 shows a typical plan for an eight-story office building in New England near the ocean. It has a rectangular footprint and the structure consists of a center concrete core and a steel framing system of wide-flange beams, girders, and columns. The floor system is composed of a composite metal decking and the façade is composed of a unitized curtain wall system. The floor-to-floor height is 15’.

Loads for a typical office floor:
live load = 249 psf.
dead load = 268 psf
