Summary

In this paper a parametric study dealing with steel and concrete composite structures for typical office buildings braced horizontally and with regularly spaced columns, based on Reference [1], is presented.

In a first step two common structural layouts for the main and secondary girders (square and rectangular) are evaluated and compared in terms of material economy, using widely used structural software. No significant differences were found in the amount of steel per square meter for these two structural beam layouts.

In a second step, the type of column layout, the spans and the structural steel class are varied as the main parameters for the chosen beam layout.

The general modeling principles for these building structures is briefly described, and for each structure considered within the parametric study the structural layout and geometry, the design criteria meeting ultimate and serviceability limit states, and the most representative internal forces are presented and discussed. This was performed according to references [2,3,4,5,6,7,8,9,10].

The steel weight of the main and secondary girders, of the columns, and of the whole structure is analyzed and presented in the form of illustrative graphics, relating the amount of steel to the span and to the structural steel class.

Finally, mathematical functions adjusted to these curves are presented, with the aim of predicting the amount of steel used for a given span in a similar layout.
