Description

A kind of steel core concrete column framed bent-Reinforced Concrete Core Walls Structure structural system
Technical field
The utility model relates to high building structure field more particularly to a kind of steel core concrete column framed bent-reinforced concretes Native core wall structure system.
Background technique
Outer framework (such as steel core concrete column frame, steel frame or reinforced concrete frame) and internal Reinforced Concrete Core Cylinder mixing tall structures tie up to has many research and engineer application both at home and abroad, using very wide especially in super high-rise building It is general.The considerations of for two defence line of antidetonation, code for structural design have a minimum value regulation to the seismic shear share rate of outer framework, and one As the node of outer frame portion (setting a roof beam in place including outline border trestle and outline border) sufficiently ensure that outline border trestle has by being rigidly connected Certain anti-side rigidity.But outer framework reaches minimum earthquake the Shear requirement and is not easy in structure design, usually needs Increase the sectional dimension of outline border trestle to meet this code requirement, the method is easy to cause " fat beams and columns ", increases construction cost And construction workload, and the column of outer framework is seriously limited away from the innovation of limit structural form.Steel core concrete column or steel frame The rigid joint of column and girder steel is usually based on welding, this causes, and site welding heavy workload, installation is complicated, working hour is long, one Determine the advantage that assembled steel grid beam is counteracted in degree.In consideration of it, developing framed bent outside the assembled connected with bolted splice, by pole The earth promotes the building industrialization level of such structural system.
With the assembled steel framed bent beam-steel core concrete column-Reinforced Concrete Core Walls Structure structural system of bolted splice, i.e., Steel core concrete column framed bent-Reinforced Concrete Core Walls Structure structural system, hence it is evident that different steel core concrete column frame-reinforced concretes Native core wall structure system.The advantage that the former utilizes Reinforced Concrete Core Walls Structure anti-side, torsional rigidity big, by steel core concrete column Mixed Architecture is formed by the bolted splice of steel framed bent beam with Reinforced Concrete Core Walls Structure.Outer bent columns are to be solely subjected to gravity " the gravity column " of load, horizontal loads are undertaken by Reinforced Concrete Core Walls Structure completely, and each component stress of structure is clear, are not had to It is entangled with and shares the adjustment of ratio in outer framework shearing, the flexibility for simplifying structured design process, improving structure design, is also structure shape The innovation of formula provides the foundation;Site welding workload, lifting construction speed can significantly be lowered, solve steel core concrete column frame The shortcomings that frame-Reinforced Concrete Core Walls Structure structural system outer frame portion speed of application lags behind Reinforced Concrete Core Walls Structure, Has the characteristics that part building industrialization construction.
Utility model content
For the technical problems in the prior art, the purpose of this utility model is: providing a kind of steel core concrete column Framed bent-Reinforced Concrete Core Walls Structure structural system, the structural system pass through the bolted splice of steel framed bent beam connecting node, greatly Ground reduces the site welding workload for even reducing or remitting steel framed bent beam, and then improves speed of application.It can also significantly relaxing layer meta position Angle limit value, the adjustment seismic design of structures Con trolling index such as floor counter-cut rates and steel core concrete column seismic shear share ratio are moved, is increased Add the structural vibration period, reduce antidetonation investment.
