Abstract
The paper briefly describes and summarizes the computed-aided analyses and design for a complex convention hotel structure in Los Angeles. Seismic analyses, upon which structural steel sizing was based, were both static and dynamic. The latter were carried out for two postulated levels of seismic ground motion, and included both response-spectrum and time-history methods.
 Columns, column splices and joint details at beam to column connections were designed using a computer program.
Highlights
The COLDES program capabilities in the version used for this project may be briefly summarized as follows:
Design and checks are in accordance with the 1963 or 1970 AISC specifications or URS/Blume1s earthquake design procedures. 3
Design loading combinations are formed directly by COLDES according to user-specified combination factors
Summary
The Bonaventure Hotel, opened in March, 1977, is located in the Bunker Hill area of Los Angeles. The four peripheral towers are located symmetrically along the diagonals of the square podium and are connected to the central tower by bridges at every level above the seventh storey and at most of the lower levels. The entire structure is supported primarily by steel framing under both vertical and lateral loads. The seventh storey there are a series of frames with moment-resisting connections in the two directions parallel to the sides of the podium (Fig. 5 ). To model the structure more accurately in the dynamic analysis, the base was assumed to be hinged, and the concrete walls along the perimeter below the second storey were included
