Overview

The composite solution was chosen considering not only the optimized best technical solution (building height, gravitational/lateral forces applied, lateral resistance system adopted), but also the total cost, erection time-consuming and time to get the raw material from providers as well.

Basic information (construction date, number of stories, gross floor area, adopted design code, engineer(s), Contractor(s), etc.)

Construction date: 2011
Number of stories: 35
Gross floor area: 167,570m2
Adopted design code: ABNT/NBR8800; ANSI/AISC360; ASCE 7
Engineer(s): Roberval José Pimenta, Alexander Galvão Martins, Gustavo Monteiro de Barros Chodraui and 3 others
Contractor(s): Codeme & Camargo Corrêa

Issue and/or innovation

Composite solution used to optimize structural performance, erection time and costs saving.

Reason for composite solution

To achieve optimized best technical solution (building height, gravitational/lateral forces applied, lateral resistance system adopted).

Specific solution/technical details

Composite steel-concrete columns (I steel shape fully encased).
Composite steel-concrete beams.
Composite slab (steel deck).
Concrete core for horizontal effects stabilization.

Impact or effectiveness

As it can be seeing in the photos, where details are presented, building structure is considered outstanding, due to vanguard engineering/fabrication solutions. The steel concrete composite solution made the project technically and economically viable comparing to other construction processes.
