Abstract:

The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss, the first of its kind, that behaves as a combined rigid frame and braced frame. Gravity loads are transferred to the exterior columns in order to resist the high overturning moments induced. Lateral loads are distributed so that they assist in resisting the overturning. Behavior of the three-panel truss is attributed to the rigid connection at the vierendeel panel. In addition, the traditional checkerboard staggering pattern was changed to provide better torsional resistance and eliminate diaphragm shear to the central bay.
