Most great universities and colleges have landmarks that become distinguishing symbols. These may be buildings, sculpture, or monuments that serve as focal points for the campus. The University of California at San Diego now has its centerpiece- a stunning cast in place concrete and glass structure to house the university's Central Library. Architects William L. Pereira and Associates of Los Angeles, seeing the need a nned for a depature from prismatic towers and cubes used in the design of most academic buildings, followed a spheroid concept to fit UCSD's particular needs. The largest portion of the building above ground is near its vertical center. The striking building is 248 feet wide at ground level, and the widest point above the ground floor is the sixth level, which is 210 feet wide. The fourth, fifth and sixth floor are cantilevered out over the 30 foot high plaza, or third level, at ground height. The seventh and eighths levels are tiered inward. The fifth, sixth, and seventh floors will house 80 percent of the main research collection, achieving the architect's goal of having most of the volumnes close to the epicenter of the 160,000 square foot building. To bear the weight and stress of the cantilevered building, the Nielsen Construction Company of San Diego, general project, cast massive bents or slope beam columns which are anchored in footings containing 1,500 cubic yards of concrete. The bents angle upward at 45 degrees to the sixth floor, and are held together by four major beams at each of the fifth and sixth levels. Because these beams literally tie the building together, up to 300 post-tensioning rods of one-fourth inch diameter high-tensile steel were strung through each of them.
