<P>PROBLEM TO BE SOLVED: To reduce the shear force caused by leverage of a steel construction part in a mixed structural beam comprising a concrete part and the steel construction part to reduce or eliminate reinforcements, thereby reducing the construction cost as well as enhancing the workability. <P>SOLUTION: A cross-sectional cutout part 3 is provided by forming a slit 31 in a web 22 of a steel construction part 12 embedded in a concrete part 11 to reduce the shear force caused by leverage of the embedded steel construction part 12 so as to reduce the amount of bar arrangement in shear reinforcements in a junction, by which the filling property in the concrete of the junction can be enhanced. The cross-sectional cutout part 3 can be cut out nearly over the overall height of the web 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
