<p>PURPOSE:To curtail construction cost by using framing materials such as truss construction, etc., and a static load operating section among reinforcing materials for woody materials, and using parts on which two or more loads in different directions among joint sections or dynamic load are acted for shape steel materials. CONSTITUTION:Woody materials are used for ridge beams 2 and main houses 3 on which mainly static load of a roof unit 1 consisting of truss construction, etc., only is acted. After that, unexpected dynamic load is applied to wind beams 4, main beams 5 and principal rafter braces 6, so that shape steel materials are used for every joint section of the ridge beams 2, beams 4 and 5 and braces 6. According to the constitution, excessive strength designs for members and joints parts can be avoided, so that member cost can be reduced.</p> |
