Technical Reports

 

Technical Report 1

 

Technical Report 1 is a study of the 1000 Connecticut Avenue's existing conditions. This report includes descriptions of the structural system; dead, live and snow load verfications; wind and seismic load calculations and gravity member spot check calculations to verify member adequacy.

Technical Report 2

Technical Report 2 is a study of 1000 Connecticut Avenue's existing floor system in addition to three alternative floor systems which were designed for this report. Each system's feasibility was determined by addressing fire protection and fire ratings, durability, weight, vibration control, structural depth, and cost. The existing floor system is a two-way flat slab and the three alternative systems chosen for design were the following:

-Composite Beam and Girder Framing with Composite Steel Deck
-Two-way Post-Tension Slab
- Composite Joist and Steel Girder Framing with Composite Steel Deck

Technical Report 3

Technical Report 3 is an analysis of 1000 Connecticut Avenue's existing lateral system. The existing lateral system consists of concrete moment frames, where the two-way flat slab floor system and concrete columns form the moment frames. To complete the lateral system analysis, wind and seismic loads were calculated, and the wind load case 1 was found to control in the North-South direction and seismic loads were found to control in the East-West direction. Further, the report analyzed the distribution of story lateral forces to the moment frames, overturning and resisting moments, building torsion, and lateral displacements and story drifts were compared to allowable code limits.
