HIGH-RISE AND SEMI-HIGH-RISE BUILDING WITH EARTHQUAKE RESISTING WALLS FORMED ON OUTRIGGERED PARTS

摘要

PURPOSE:To contrive economical design by making outriggered parts share horizontal force, by a method wherein earthquake resisting walls are formed over planes of structure including girders at the end of slabs formed being supported by girders outriggered from a building. CONSTITUTION:At the outside of a plane of structure, consisting of outside column 2 and girders 6, of a building, outriggered, girders 3 are provided for the second story and upward. These outriggered girders are spanned with beams 31. Then, slabs 4 are formed by extensions of slabs 7 that are extended outwardly. Between the beams 31 at the outside edge of the slab 4 of each story, earthquake resisting walls 10 and earthquake resisting walls 20 including girders 3 are respectively provided. Shearing force to be borne by the earthquake resisting wall 10 and 20 installed at the outriggered parts works to reduce, by the same amount, shearing force to be applied to rigid frame parts of the building proper. Consequently, cross sections of column and girder members can be designed economically.
