Ductile connection construction and construction method for assembly type vertical component and foundation

Abstract

The invention discloses a ductile connection construction and construction method for an assembly type vertical component and a foundation. A grout sleeve is embedded in concrete of the cast-in-placereinforced concrete foundation, thus ductile connection of connection nodes between the cast-in-place reinforced concrete foundation and the reinforced concrete precast vertical component is achievedon the premise that a connecting rebar of the cast-in-place reinforced concrete foundation can be connected with a longitudinal bar of the reinforced concrete precast vertical component through the grout sleeve, the effect that rebar internal force in the connection node area can be effectively transmitted is ensured so that when a building encounters a rare earthquake, a plastic hinge can be generated in the column bottom area above the connection nodes, the problems that when the grout sleeve is embedded in the column bottom, the bottom of the vertical component is connected with the foundation, thus the plastic hinge is difficult to generate, and consequently when the rare earthquake occurs, brittle failure occurs are avoided, and the effect that damage to the bottom of the vertical component is ductile damage is ensured. The ductile connection construction and the construction method for the assembly type vertical component and the foundation have the advantages that overall stressed performance of a frame structure and ductile anti-seismic performance can be improved.

Description

technical field [0001] The invention relates to a ductile connection structure and a construction method of an assembled vertical member and a foundation. Background technique [0002] Prefabricated reinforced concrete structures have already had many practical applications and relatively mature technical research in developed countries such as Europe, America and Japan. In recent years, the country has developed green buildings, vigorously developed prefabricated buildings, and promoted the transformation and upgrading of the construction industry. With the acceleration of the process of "construction industrialization and housing industrialization" in my country, the application of prefabricated structural buildings is becoming more and more extensive, and the practical application and theoretical research of prefabricated structural buildings in China is deepening. [0003] The connection of prefabricated components in prefabricated concrete structures is one of the key ...

AI Technical Summary

Problems solved by technology

Since the grouting sleeve is not allowed to yield at each stress stage of the structure, that is, it cannot cooperate with the stressed steel bar to produce plastic deformation, so this connection method cannot form a plastic hinge at the connection part
