METHOD OF REDUCING DIFFERENTIAL SHORTENING BETWEEN VERTICAL MEMBER IN SUPER TALL BUILDING USING WATER-PROOF MATERIAL AND VERTICAL MEMBER IN SUPER TALL BUILDING USING WATER-PROOF MATERIAL

摘要

PURPOSE: A differential shortening reduction method by using a waterproofing material among vertical materials and a vertical material for a skyscraper by using waterproofing material are provided to control an evaporation of the moisture and drying shrinkage in advance by spreading a waterproofing material on the surface of vertical materials. CONSTITUTION: A differential shortening reduction method by using a waterproofing material among vertical materials and a vertical material for a skyscraper by using waterproofing material are as follows. Vertical materials predicted to be needed a correction with respect to a vertical shrinkage caused by a differential shortening are selected through a structural analysis based on design data of a skyscraper having a plurality of concrete vertical members(C). The vertical shrinkage amounts of each selected vertical material are calculated. Each correction amount of the vertical shrinkage for selected vertical materials except drying shrinkage amounts from the vertical shortening amounts is decided. Concrete is placed to form the selected vertical materials by being reflected the vertical shortening amount. Waterproofing material(WP) for preventing the dry shrinkage is spread on the surfaces of the selected vertical materials.
