Tests were made at the Portland Cement Association Laboratories regarding the elastic and time-dependedt shortening of reinforced lightweight concrete columns which were fabricated and loaded to simulate construction conditions encountered in a 50-story concrete building 714 ft (218 m) tall. The measured data from these incrementally loaded columns show low creep when the load is applied at a realistic rate. A 3-year field investigation of the actual structure will be undertaken and comparision between laboratory and field data will be made. Such comparisions wil provide data toward developing improved design concepts for ultra-high-rise concrete buildings.

A brief history of the evolution of structural lightweight concrete in building codes is presented. The special provisions for structural lightweight concrete contained in ACI 318-63 have been extended and modified in ACI 318-71. These changes, particularly with regard to quality control, deflection, flexural strength, diagonal tension, and development length are discussed.

This paper presents data on the fire resistance of concretes having oven dry unit weights in the range of 30 to 100 lb per cu ft (500 to 1600 kg/m3). . .Design charts for estimating the fire endurance of two-cource floors and roofs are discussed. Relationships between moisture content and relative humidity of fire test specimens are presented.
