Abstract
Disclosed herein are support column structures which can be used to support bridges, buildings or other structures. In some cases, a support column structure can be deconstructable and include one or more removable elements. In some cases, a support column structure can include shape memory alloy reinforcing bars. In some cases, a removable element of a support column structure can include an engineered cementitious composite. In some cases, a removable element includes one or more sleeves to separate an engineered cementitious composite from one or more shape memory alloy reinforcing bars. Methods include assembling and disassembling a support column structure.
Claims20
A support column structure, comprising:
- a base portion having a top surface;
- a column portion having a bottom surface;
- and
- a removable portion comprising an engineered cementitious composite;
- wherein the removable portion comprises a top surface removably coupled to the bottom surface of the column portion;
- and
- wherein the removable portion comprises a bottom surface removably coupled to the top surface of the base portion.
A support column structure, comprising:
- a base portion having a top portion;
- a column portion having a bottom portion;
- a removable portion comprising a main body portion and a plurality of sleeves;
- and
- a plurality of reinforcing bars;
- wherein each of the reinforcing bars extends from the bottom portion of the column portion, through a respective sleeve of the removable portion, to the top portion of the base portion;
- and
- wherein the sleeves separate the respective reinforcing bars from the main body portion of the removable portion such that the reinforcing bars are not in contact with the main body portion of the removable portion.
A method of assembling a support column structure, comprising:
- positioning a base portion to act as a foundation for the support column structure;
- coupling a plurality of reinforcing bars to the base portion;
- situating a removable element on the base portion such that the reinforcing bars extend through a main body of the removable element, the main body comprising an engineered cementitious composite;
- coupling the reinforcing bars to the removable element such that the removable element is restrained against movement with respect to the base portion;
- situating a column portion on the removable element;
- and
- coupling the column portion to the removable element such that the column portion is restrained against movement with respect to the removable portion.
A method of disassembling a support column structure comprising a base portion, a removable portion, a column portion, and a plurality of shape memory alloy reinforcing bars, comprising:
- de-coupling the column portion from the removable portion;
- lifting the column portion off the removable portion;
- de-coupling the removable portion from the plurality of shape memory alloy reinforcing bars, the shape memory alloy reinforcing bars being coupled to the base portion;
- and
- lifting the removable portion off the base portion.
