Using the concept of the artificial neural networks and the results of the performed numerical analyses as input parameters, the prediction model for defining the fire resistance of RC columns incorporated in walls and exposed to standard fire from one side, has been made. A short description of the numerical analyses of columns exposed to standard fire ISO 834, conducted by the computer software FIRE are presented in this paper. The software is capable of predicting the nonlinear response of reinforced concrete elements and plane frame structures subjected to fire loading, carrying out the nonlinear transient heat flow analysis and nonlinear stress-strain response associated with fire.
Customer Relationship Management (CRM) is a modern business strategy which creates and maintain long term and profitable relations with the buyers. CRM serves for planning and maintaining processes of sales and strengthening competitiveness by registering all interactions of the company with its buyers and suppliers. This system collects and consolidates information from various sources within the company, and where it is possible, they collect information from the company's surroundings in order to offer unique image about each single client, in the real time. Aim of the paper is to show that CRM strategy can be successfully implemented in doing business in the area of civil engineering, so that good business results can be generated on that basis and strengthen competitive ability. Achieving close relations with customers represents main tools for obtaining competitive advantages, thus this paper will show the significance of setting up these relations with customers as well as ways how CRM can contribute to improving better operations on the long run.
Changing a layer of weak soil in deformed foundation with a compacted soil bed consisted of various strong materials (sand, gravel, pebble-gravel, production waste materials). Existing calculation methods and techniques to build compacted soil beds based on weak highly compressive soils do not meet up-to-date requirements. Calculation methods used the dimensions of compacted beds quite often appear to be overestimated, and this results in increase in costs and working hours needed to build artificial foundation. The paper presents the possibility of using reinforced soil beds as an efficient method to build artificial foundation based on weak soils.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
