Seismic analysis of the ‘South Gate’ tall building according to Eurocode 8

The tallest building designed in Poznań (western part of Poland) is the case study. The analysed building is a multifunctional office centre with the heliport on the top, called the ‘South Gate’. The main structure is the RC slab and column system with shear walls and cores. After many static analyses the seismic analysis, based on damage limitation state according to Eurocode 8, was made. The analysis, in which a continuous–discrete approach and the response spectrum technique were applied, was carried out by means of the DAMB program as part of an integrated system. The allowable design ground acceleration was evaluated. Copyright © 2004 John Wiley & Sons, Ltd.     

The application of ‘least-cost’ modelling as a functional landscape model

The growing awareness of the adverse effects of habitat fragmentation on natural systems has resulted in a rapidly increasing number of actions to reduce current fragmentation of natural systems as well as a growing demand for tools to predict and evaluate the effect of changes in the landscape on connectivity in the natural world. Recent studies used ‘least-cost’ modelling (available as a toolbox in GIS-systems) to calculate ‘effective distance’, a measure for distance modified with the cost to move between habitat patches based on detailed geographical information on the landscape as well as behavioural aspects of the organisms studied. We applied the method to a virtual landscape and a small scaled agricultural system subject to different scenarios in a land re-allotment project. We discuss the importance of technical aspects and ecological assumption underlying this modelling method. The model is shown to be a flexible tool to model functional connectivity in the study of the relation between landscape and mobility of organisms as well as in scenario building and evaluation in wild life protection projects and applied land management projects. Since ‘effective distance’ has the same units as Euclidean distance (m), this effective distance may be a straightforward way to include landscape and behavioural aspects in other models which include distance as a measure for isolation. We show the importance of the ‘ecological’ quality of the input maps and the choice of relevant landscape features and resistance values.

The concept of a ‘concentration town’

The Netherlands Habitat Commission was founded to coordinate all activities during the International Year of Shelter for the Homeless (1987). Over the years in the Netherlands, both on the governmental and nongovernmental level, attention to and support for the urban problems in the Third World has significantly increased. The Commission had taken the initiative of developing a so called concentration town project, based on the concept that targeting aid to one city will strengthen the impact of each individual project. A pilot project is being established in the Indian city of Bangalore. The results so far are promising. Through this project the NHC would like to show how use can be made of the growing interest in the plight of the urban poor in the Third World.

‘Management by projects’: the management approach for the future

The trend toward the project-oriented company, performing simultaneously a network of internal and external projects, creates the demand for the management approach ‘Management by Projects’. The specific feature of ‘management by projects’ is that the management of single projects, the management of the network of projects and the management of the relationships between the company and the single projects are considered. For the successful management of the project-oriented company, instruments of ‘Management by Projects’ are presented.

The application of direct search optimisation to structural design

Development of an optimisation method suited to structural engineering design applications is described briefly. The method is essentially a conventional direct-search technique with exterior penalty constraints but uses variable penalty factors during the search to improve mobility between feasible regions. The method is illustrated by application to design of a composite box-girder footbridge, employing eight design variables and nineteen constraints, and the results are used to demonstrate the importance of considering sub-optima as well as the global optimum. The usefulness of univariant parameter/cost relationships in the region of global and local optimum points, derived as an intrinsic part of the optimisation process, is also stressed.
