Executive Summary

The Executive Tower is a 11 story office structure in the down town area of Washington DC.   Constructed of cast in place concrete, Executive Tower consists of aproximately 30 ft spans utilizing a concrete flat slab with drop panel structural system.   In the first semester, the Executive Tower's structure was studied and restudied looking at altanive systems for gravity and lateral loads.  The loads themselves were studied by the student to insure they match up with the loads used in the design of the actual building.  Small difference that were found in these calculations are assumed to be neglectible or experience the student will gain through his senior year.  The following semester is will be spent carrying out the proposal goals set by the students.  In the Executive Tower, it is planned to design a 12th story typical to floor 3-9 in DC's strict height limitations.  First a design of the structural system by adding Post Tensioning in order to reduce the floor thicknesses.  Two breadth projects are also centered around this goals of shortening the building.  First, a mechanical redesign will ulitize heating and cooling systems with thinner duct work.  Second, a redesign of the first floor to recess the aproximately 2'-6" without taking away from the existing exterior skin.
