Comparative life cycle costs for new steel portal frame building systems

Reliability Analysis of Steel Building Frame Under Earthquake Forces

A simplified fragility analysis of steel building frame is presented which can be used for preliminary estimate of its probability of failure. The risk analysis procedure uses the format of probabilistic Risk Analysis (PRA) and considers band limited white noise at the bed rock as the seismic input. The steel building frame is modeled as a 2D frame and Pushover analysis is then carried out to o...

Building a Semantic-Web Portal Using Frame-based System

In this paper we report employing frame-based system as the basis to build up a ontology-based portal. The basic idea is to transform the ontology schema and instances collected from various digital library sites using the semantics of the frame-based system. The service programs written using the frame-based reasoning formalism thus can make use the knowledge.

Determination of Optimum Insulation Thickness for Building Walls in Iran Using Life Cycle Cost Analysis

Air-Conditioning (AC) systems are responsible for a considerable portion of the energy consumption in buildings located in high cooling load requiring regions of Iran. In addition, the heat flow through the buildingschr('39') external walls plays a major role in cooling load estimations for the countrychr('39')s hot regions. Therefore, application of insulation materials in external walls has g...

BUILDING LIFE CYCLE. Tools for Building Components and Industrial Products

In the research activity carried out in this PhD’s Project, the Ecodesign approaches and tools are transferred into the Building Sector in order to check the common concepts between these two cultures. This main goal is justified by the awareness that in the building sector several changes have been done. First of all to conform itself to Sustainable principles, and then, in wide use of buildin...
