Speech Title: Mechanical Properties of Aged Paper Tube of Paper Dome

Abstract: Paper tubes, also known as hollow paper cores, have been used throughout the world in the construction industry as formwork for circular columns and are the most popular products of the paper industry used by famous Japanese architect Shigeru Ban’s architectural projects. Paper Dome is a church made of giant hollow paper tube structure supported by an oval of 58 tubes, 5.0 meters in height. The outer diameter of tube is about 33 cm and the wall thickness of paper is about 1.5 cm. A laboratory investigation was conducted to evaluate the mechanical properties of paper tube of paper Dome used over 10 years in Japan. These experimental tests include compressive strength, tensile elongation test, split tensile test, flat crush compressive test, hardness test, and bending strength test for the elastic modulus. These test results indicate that the 10-year-old paper tubes can still be used in large structures for church and until now, the paper tube materials has endured over 20 years in-service in Taiwan environment. The expected lifetime of the paper tube structure affected by the environmental impact estimated at ten to twenty years. Therefore, the paper Dome maybe still be required for conducting a preliminary inspection and maintains public safety in the further.
