INTRODUCTION Object-oriented (OO) programming languages and OO analysis and design techniques influence data base systems design and development. The inevitable result is the object-oriented data base management system (OODBMS). Many of the established data base vendors are incorporating objectoriented concepts into their products in an effort to facilitate data base design and development in t...

A computer-aided design tool for assisting the designer to set appropriate passive solar systems for heating and cooling is presented. The system is based on a knowledge base oriented design process (KBDP). The knowledge base stores design guidelines and procedural methods for determining the passive systems that best suit the local climatic conditions. This tool is aimed to be used already at ...

spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...
