Multi-objective optimization for the conceptual design of structures
… tools, fast and accurate predictions of building performance are increasingly possible. In parallel, the expectations of a high-performance building have been rising in contemporary architecture, as designers must synthesize many inputs to arrive at a design that fulfills a wide range …

Optimum design of structures with stability constraints using the evolutionary optimisation method
In the past most of the works on structural optimisation have been based on either mathematical programming or optimality criteria methods and have mainly concentrated on static responses of structures. These optimisation methods are mathematically complex and have limited applications. A novel …

Improved seismic design of structures using risk-targeting and cost-minimization considerations
… thesis addresses various topics in the context of seismic design of structures with risk and loss considerations. Three design philosophies are investigated: the one based on uniform-hazard spectra, the risk-targeting technique, and an approach that minimizes the life-cycle costs. While the …

Integrated Optimal Design of Structures Subjected to Alternate Loads Using Geometric Programming
… conditions in the integrated optimum structural design is investigated. The method developed, called move coordination, consists of formulating the large optimization problem in the form of smaller subproblems based on the load conditions. This is accomplished by allowing the structural design …

Life-Cycle Cost-Based Optimal Seismic Design of Structures with Energy Dissipation Devices
Seismic designs of building structures are currently made based on the design criterion of life-safety and this requires that the structures do not collapse to compromise safety of people in the structure, but they can be designed to experience some damage. However, this design approach has allowed …

Optimisation et prédimensionnement des treillis, arcs, poutres et câbles sur base d'indicateurs morphologiques; application aux structures soumises en partie ou en totalité au flambement
This thesis is about the optimization and design of structures (trusses, cables, arches, beams) thanks to dimensionless numbers called morphological indicators. A good summary of this method can be read in the inroduction and conclusion of the following article: Latteur Pierre, Feron Jonas, Denoël …

Evaluation of Structural Response and Damage Resulting From Earthquake Ground Motion
The design of structures to limit or preclude strong response and damage from earthquake ground motion is a complex problem and is the subject of this thesis. The factors leading to strong response are not well understood and clearly involve more than peak acceleration and yield level. Present …

O teorema da acomodação e suas aplicações
… work, the basic concepts related to the plastic design of structures are reviewed. The advantages and some methods of the plastic design are presented. The shake-down problem is studied. The tests of metalic frames carried out by NEAL and SYMONDS are shown and the shake-down theorem is proved, in …

Computer Aided Engineering Problems and Prospects
We are now entering the third decade of engineering computer applications. In the past twenty years, the computer has become a requisite tool in civil engineering. One is hard-pressed to imagine the analysis and design of structures such as high-rise buildings (exemplified by the Sears Tower, John …

On The Shear Strength Of Partially Grouted Concrete Masonry
Masonry shear walls are one of the most common structural elements in buildings. The in-plane shear capacity of load-bearing walls is of great importance in the seismic design of structures. This study focuses on the shear behaviour of wide-spaced reinforced partially grouted (WRPG) concrete …

Approximation algorithms for rapid evaluation and optimization of architectural and civil structures
This thesis explores the use of approximation algorithms, sometimes called surrogate modelling, in the early-stage design of structures. The use of approximation models to evaluate design performance scores rapidly could lead to a more in-depth exploration of a design space and its trade-offs and …

Geometrical optimization of arched structures under stochastic loading
… the moment-optimized shape y(x) for arched structures under unpredictable loading scenarios. A frame geometry optimization derivation is presented that demonstrates the relationship between certain unpredicted loads and an equivalent guaranteed loading condition that is more easily solvable …

The effect of reinforcement on loadbearing capacity of structural glass
The transparent property of glass makes it a favored choice of material in the design of structures because it maximizes light and creates an illusion of larger spaces. However, it is a very brittle, making it difficult to use as a common building material. Laminated glass significantly improves …

An overview of progressive collapse in structural systems
… that abnormal loads need to be considered in the design of structures so that progressive collapse can be prevented. Building collapses such as the Ronan Point, Alfred P. Murrah, and World Trade Center have shown the catastrophic nature of progressive collapse and with an increasing trend towards …

A comparative study of structural material for dome construction
… free space is a pervasive goal in the design of structures intended to provide shelter and protection. This is especially essential for venues such as athletics, spectator activities, and large congregations. The need for such space is constrained by structural feasibility and costs of …

An Approach to Concept Development for Compliant Mechanisms Possessing High Coefficients of Restitution
The design of structures and mechanisms subject to impact loading has historically involved designing in such a way as to minimize damage induced by the impact. This has historically been accomplished by absorbing and dissipating the energy of the impact. However, in some applications it is …
