Abstract:
The paper discusses the need for interaction between the engineer and his fellow professionals. In particular, refeences made to the role of the structural engineer in the design of buildings, and the liaison which should take place with architects and other members of the design team. The team approach to design is discussed, and some suggestions are made with respect to the disciplines which may be represented on a project team. Examples are given of projects in which the engineer has been instrumental in determining the final results.

A comparison is made of the reinforced concrete Synopsis: design of two long low-rise corporate headquarter buildings in Houston. Both buildings utilize pour strips to completely eliminate in one case and minimize in the second case the number of expansion joints. The process which was followed to eliminate the expansion joints included a comprehensive computer analysis of temperature effects. This analysis gave the forces for which additional reinforcing was required. Strips of concrete through the buildings at all levels were omitted to allow the initial shrinkage and creep to take place and then the strips were filled in. One building was completed in 1977 and has developed no significant cracks while the second building is now under construction.

During the last twenty-five years many structural innovations have been made relating to reinforced concrete systems for buildings. Among many factors that affect innovative developments by engineers, an extremely significant one is the educational back-ground and environment during the formative years in the university. This particular factor, although often overlooked, needs to be recognized by the educational institutions. The author discusses the possible impact of a creative teacher on a student's innovative approach in his later career, and as an example, traces his own occasional success at innovations to such a teacher at the University of Illinois where he did his graduate studies. A special tribute is therefore offered to Prof. Chester A. Siess whose constant encouragement to think critically in a creative way greatly affected the author's professional career.

The main features of a construction system, know as the EAG System and developed to build from single housing units to multistory dwel-l ings, are described. This includes the fabrication of the basic construction elements, their assembling to form modules, the finishing operations at the factory and the erection at the construction site. The System structural pro-blems- are discussed, and a test program planned to answer some structural questions is far, and reviewed in some detail. The which cover the behavior of floor results of the tests panels in flexure performed so and shear, wall panels under lateral aspects of loads, diagonaI the flexural strength of panel braced frames, are presented.

The "haunched girder" system is a reinforced concrete system used to frame floors in high-rise concrete office buildings. The system consists of conventional pan-joists framing into a girder whose depth is equal to the depth of the joists in the center two-thirds of its span and then the depth of the girder increases toward the columns. The increased depth at the columns, where moments and shears are maximum, reduces both concrete and reinforcing requirements. The shallow depth in the middle helps to reduce the overall volume of the building. The system has been successfully used in office buildings ranging from 10 to 25 stories tall in Houston.
