Title:
FABRIC-REINFORCED ECC-STEEL PIPE-STEEL FRAME COMPOSITE MEMBER AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/003862
Kind Code:
A1
Abstract:
A fabric-reinforced ECC-steel pipe-steel frame composite member and a fabrication method therefor, the composite member comprising: a thin-walled steel pipe (3), a fabric-reinforced ECC coated on an outer side of the thin-walled steel pipe (3), a structural steel frame (2) arranged within the thin-walled steel pipe (3) and concrete (1) poured into the thin-walled steel pipe (3). The fabric-reinforced ECC is composed of an ECC (5) and a fiber-woven mesh (4), and the geometric centroids of the thin-walled steel pipe (3) and the structural steel frame (2) coincide. The fabrication method comprises: first pouring the concrete (1) into the thin-walled steel pipe (3), then spraying or applying the ECC (5) onto an outer wall of the thin-walled steel pipe (3), annularly wrapping the fiber-woven mesh (4), and then spraying or applying the ECC (5) onto a surface of the woven mesh (4), as well as a curing step. In the described composite member and fabrication method, the fabric-reinforced ECC is used to annularly wrap the thin-walled steel pipe (3) so that the composite member has high durability, fire resistance and bearing capacity.
