SYNOPSIS

Research into the behaviour of concrete structures and publication of papers in international journals and as conference proceedings.

PROJECT DESCRIPTION

Masera Engineering Group has collaborated on this project with Professor Ferro’s Research Group in the Structural, Geotechnical and Building Engineering Department of the Polytechnic University of Turin.

Diagrid structures, like all tubular configurations, utilize the overall building plan dimension to counteract overturning moment and provide flexural rigidity. However, this potential bending efficiency of tubular configurations is never fully achievable due to shear deformations that arise in the building “webs”; in this regard, diagrid systems, which provide shear resistance and rigidity by means of axial action in the diagonal members, rather than bending moment in beams and columns, allow for almost full exploitation of theoretical bending resistance.

This is the main reason underlying the extraordinary efficiency of diagrid systems. Since the diagrid is a triangulated configuration of structural members, the geometry of the single module plays a major role in external axial force distribution, as well as in conferring global shear and bending rigidity on the building structure. In this project diagrid system analysis is applied to an irregular shaped high-rise building in Casablanca, the New Marina Casablanca Tower.

This 167 m high-rise concrete building was designed by Arji Ali and has 42 storeys. The unique architectural feature of the tower is its twisting shape. While the skyscraper’s 42 floorplates are all identical, each is slightly rotated by 3 degrees against the floor below, resulting in a full 140-degree twist over the course of the tower’s 167 meter height. The facades consist of a modular system of triangular glass panels held together in an aluminium frame.
