The Influence of Mass Loss on Wooden Elements Case Study

Data publikacji: 02 Mar 2019
Zakres stron: 1 - 9

Abstrakt

Abstract

The durability of wooden structures is a subject of great interest because a better understanding of the evolution of wooden elements is needed, together with the factors that intervene in the degradation process and the manner in which they can be prevented. The exposure time of structures to environmental variations is important because the presence of humidity is affecting wooden elements the most. Their exposure to humid surroundings or in which temperature and humidity variations are not constant, increases the moisture content of wood and leads to the formation of biological environments that attack the wood and reduce its resistance, intervening in the building safety and utility. The current study follows the evolution of a wooden structure subjected to changes of the transversal section due to the presence of humidity until the moment in which the wooden piece does not verify anymore the safety conditions from the calculations for compression, tension and bending.

Modeling and Analyzing the Factors Affecting the Mortality of Pedestrians in Urban Accidents

Data publikacji: 02 Mar 2019
Zakres stron: 10 - 21

Abstrakt

Abstract

The nature of urban and rural accidents has been different from each other in some of the factors and even the severity of damage rate, mayhem, and death. In this research, using statistical methods and binary logistic regression model, we have addressed to analyze important parameters such as age, gender, education level, the color of the pedestrian dress, season of accident, time of accident, the speed of the vehicle colliding with pedestrians and road surface conditions at the time of accident on the way of death (at the scene of the incident or in the hospital) pedestrians who have been traumatized. After the creation of the binary logistic regression model, it was determined that only the parameters of speed and the accident time have been significant in the level less than 5%. And other parameters such as age, gender, the season of accident occurrence, the color of the pedestrian dress, road surface conditions and education level had no significant effect in terms of statistical on the incidence of mortality arising from a pedestrian accident with the motor vehicle. The results revealed that by adopting decisions related to the traffic calming, attention to passages lighting and brightness the mortality rate of a pedestrian due to the urban accidents can be reduced.
