Abstract

PURPOSE: To make it possible to design a roof with a small section of member in comparison with a relatively large-sized cantilever type roof such as soccer stadium, etc., and to enable safe construction against upward load suck as blowing up wind load, etc. CONSTITUTION: A cantilevered roof 1 covering upward of a lower structure skeleton B in a stadium is connected to bearing posts 2 erected to the peripheral surface of the lower structure skeleton B in the basic end of the roof with pins so as to make it possible to incline in the vertical direction, and posts 4 and 4' are connected to the front end of the roof 1 with pins so as to make it possible to incline in the horizontal direction. Cables 6-A bearing the roof 1 in the vicinity of the lower parts of the posts are respectively tensioned to the ground foundation 9 through the bearing posts 2 to resist downward load such as dead-weight, etc. Cables 6-C are connected between the upper parts of a pair of up and down posts 4 and 4', and cables 6-B from the upper parts of the posts are respectively tensioned to the ground foundation 9 through the bearing posts 2 to resist load acting upward of blowing up wind load, etc. An unstable phenomenon caused by load acting unequally on both right and left roofs with diagonal line shaped cables 6-C' in a side view can be prevented.

2. Description of the Related Art In recent years, domestic and international soccer competitions have become popular at various places, and large stadiums capable of accommodating a large number of spectators have been constructed. Of these, many facilities have been built to cover the entire stadium with a roof, but in soccer and other ball games, since the game is played on a natural lawn, the entire stadium is not covered with a roof, only the spectator seats are covered with a roof. It is common to cover. In addition, it is desirable that no columns be provided in the audience seats so as not to obstruct the view of the audience.
