The Method of Predicting the Extent of Changes in the Performance Characteristics of Residential Buildings

Abstract

Accordingly to recommendations set out by standards, degradation curves which will serve as a tool facilitating decision-making regarding renovation works ought to be developed. The article presents the proposal of a model for predicting the aging of a residential building. The proposed PRRD (Prediction of Reliability According to Rayleigh Distribution) model determines the performance characteristics of a building over the full period of its use. PRRD accounts for the life spans of individual building components. Additionally introduced in the model were supplements accounting for the intensity of changes in the building and its surroundings. The developed method of the non-linear degradation process of a building accounts for the role and weights of individual building components as well as the intensity of significant factors influencing the aging process. The presented methodology of the description of changes in the performance characteristics over the course of using a building will be a diagnostic process of predicting the technical state of a building. The proposed predictions can serve as the basis for making the right strategic decisions when planning renovation works in residential buildings.

Traffic Analysis and Pavement Technology as a Tool for Urban Noise Control

Traffic related noise is currently considered as an environmental pollution. Paper presents results of multidirectional study attempting to serve urban traffic without the need to erect noise barriers interfering urban space. Initial concept of the road expansion included construction of 1000 m of noise barriers dividing city space. Improvement in the acoustic conditions after construction completion is possible due to the applied noise protection measures: vehicle speed limit, smooth of traffic flow, use of road pavement of reduced noise emission and the technical improvement of the tramway.

Problems of the Selection of Construction Technology for Structures in the Centres of Urban Agglomerations

Abstract

The goal of the article is the diagnosis and presentation of the problems of the selection of construction technologies for buildings being built in the centres of urban agglomerations. The survey and literature studies that were performed show that the process of selecting these technologies is difficult due to a series of very different difficulties associated with constructing a structure in a city centre and which are sometimes hard to foresee. At the same time there is a lack of decision-making support tools dedicated to the selection of construction technologies that would take into account the problems that occur during the construction of buildings in city centres. The study shows the need to discuss the subject of developing a mathematical model and a decisionmaking support tool based on said model to that end.

Simulation of Seismic Response of Reinforced Concrete Beam-Column Joints with Nurbs Surface Fitting

Abstract

This paper presents an approach based on NURBS (non-uniform rational B-splines) to achieve a seismic response surface (SRS) from a group of points obtained by using an analytical model of RC joints. NURBS based on the genetic algorithm is an important mathematical tool and consists of generalizations of Bezier curves and surfaces and B-splines. Generally, the accuracy of the design process of joints depends on the number of control points that are captured in the results of experimental research on real specimens. The values obtained from the specimens are the best tools to use in seismic analysis, though more expensive when compared to values simulated by SRSs. The SRS proposed in this paper can be applied to obtain surfaces that show site effect results on destructions of beam-column joint, taking into account different site conditions for a specific earthquake. The efficiency of this approach is demonstrated by the retrieval of simulated-versus-analytical results.
