The behavior of framed tube structures is discussed from an overall structural system point of view. The influence of various structural parameters affecting tubular behavior is emphasized. The concept of the equivalent reduced plane frame modeling technique is used for developing a series of "influence" curves for the preliminary analysis and design. An example problem is worked out using these curves and the results are compared with a more exact solution of a computer analysis.

SP36 Presents selected papers dealing with the structural analysis and design of tall reinforced concrete buildings. Subjects covered include: frame-shear wall systems; framed tube structures, optimization, load distribution analysis, and symmetric shear wall analysis. Four papers dealing with various aspects of the problems of constructing tall buildings in sesmic areas are also included.

The process of practical design optimization of high-rise concrete buildings is discussed from an overall systems point of view.

A method is presented for the analysis of the distribution of lateral loads amongst the shear walls of a three-dimensional multi-storey [sic] building subjected to both bending and torsion.

This paper presents a condensed state-of-the-art report on the philosophy underlying the design for earthquake resistance of multistory structures in reinforced concrete.
