Title:
TOWER-LIKE STRUCTURE, AND METHOD FOR BUILDING SAME
Document Type and Number:
WIPO Patent Application WO/2010/044380
Kind Code:
A1
Abstract:
Provided is a tower-like structure made of concrete which is less susceptible to bending fracture, and also provided is a method for building a tower-like structure. Pre-stress is introduced in the vertical direction to a tower-like structure of reinforce concrete standing on a foundation in order to prevent cracking of concrete at a tensile stress generating portion of the tower-like structure.  When pre-stress is introduced in the circumferential direction to the tower-like structure so that confined effect is exhibited, compression strength, flexural strength and deformation performance of the tower-like structure can be enhanced.  A tower-like structure made of concrete which is less susceptible to bending fracture can be built by these pre-stress introduction effects.
