Abstract: Poultry houses should be economical and should demonstrate adequate resistance and safety. In poultry houses, generally truss systems or frames are used as the supporting systems and reinforced concrete and steel sections are used as construction materials. In this study, 45 poultry houses from 25 commercial enterprises within the study area were selected as the material. They were evaluated based on their capacities, system designs and construction material used in their supporting system. Initially, construction materials selected for supporting systems and their dimensions were determined and their structural sufficiencies were evaluated. Then, seven model poultry house were developed by taking the current conditions of the enterprises and related literatures into consideration. Three different material combinations were considered for supporting system of each model developed: Steel truss - reinforced concrete column, steel truss - steel column and frame system. Thus, total of 21 different combinations for 7 models were evaluated. Depending on supporting system characteristics, load analysis and statical calculations were carried out for each model and supporting systems were dimensioned based on results obtained from statical solutions and economical comparisons were carried out among them. It is believed that results of this study may contribute significant perspectives for the project engineers in poultry housing systems.
