A comparison of methods for using genetic algorithms to guide parametric associative design

VAN BUELOW, Peter (Editorial Universitat Politècnica de València, 2009-12-18)

The use of parametric software such as Generative Components (Bentley Systems), Grasshopper (Robert NcNeel), Digital Project (Gehry Technologies - Dassault Systemes) and others, has revealed an ever larger variety of ...
Comparison of nonlinear solution between tangential stiffness equation and third order nonlinear equation on bifurcation load of space trusses

KIM, Nam-Seok; KIM, Seung-Deog (Editorial Universitat Politècnica de València, 2009-12-15)

A lot of research has been carried out in the relation of structural optimisation and form finding processes of architectural and engineering building projects and only recently the consideration of other performance ...
Computational Structural Form Finding and Optimization of Shell Structures

BORGART, Andrew; TIGGELER, Lonneke (Editorial Universitat Politècnica de València, 2010-01-14)

The purpose of this research is to analyze the structural behaviour of shell structures by studying the way (applied) loads naturally flow through shell structures to their supports and relating this flow off forces to ...
Computer analysis and design of concrete shells roofs

SAMARTIN, Avelino; ABEL, John F. (Editorial Universitat Politècnica de València, 2009-11-25)

This paper is a preliminary version of Chapter 3 of a State-of-the-Art Report by the IASS Working Group 5: Concrete Shell Roofs. The intention of this chapter is to set forth for those who intend to design concrete shell ...
A concept of a beam prestressed by bending: Application to a footbridge in composite materials

BAVEREL, Oliver; CARON, Jean-François (Editorial Universitat Politècnica de València, 2009-12-11)

This paper proposes a concept of a beam prestressed by bending. An application through an example of footbridge with three supports is shown and illustrated. By bending a beam with a central cable, this cable will be in ...
Concept, design and realization of the Moses Mabhida Stadium, Durban, South Africa for the Football World Cup 2010

BALZ, Markus; GÖPPERT, Knut; KEMMLER, Roman (Editorial Universitat Politècnica de València, 2010-02-09)

As part of the City of Durban's redevelopment program the projected World Cup stadium was chosen to create an icon for the KwaZulu Natal region and Durban, being the 2nd largest city of South Africa. The ambitious plan ...
