Pressure ratio is 0.5-1.0, and 1.0 hereinafter, preferably 0.8, the antidetonation section checking of the wall 1 meets SR/ γ RE, described for control
The concrete pulling stress of girderless floor 2 should ensure that less than or equal to zero.The arrangement of reinforcement of the girderless floor 2 is according to calculated result and building
The requirement ratio of reinforcement of earthquake resistant design code increases by 0.05.Other Components Analysis calculated results should ensure that in current national codes requirement
Within.
The present invention uses the multistory large spaces of " free profile waves support column 3+ concrete side to stress balance wall 1 "
Architectural structure system is limited derived from the space of multistory large spaces building structure type selecting.Support column 3 in the building system is with freedom
Random state arrangement is designed to only hold in system since its very thin column section cannot undertake enough anti-side rigidities
Carry on a shoulder pole the swing column of vertical force.Since support column 3 does not have to undertake any horizontal force, slenderness ratio be can be far smaller than that in ordinary construction
Pillar.3 one side of support column arranged at random can be directed to the different arrangements for needing to form adaptability, on the other hand
The permeability of large space is guaranteed, and has moulded with innovative space intention.
The concrete side to the space that the wall 1 of stress balance is formed can for provide in the building system vertical transportation,
The vertical member of pipe well.As the component part of composite construction entirety, concrete wall 1 becomes main Lateral Resistant System.It is mixed
Coagulate the settable fashioned iron sleeper in 1 inside of cob wall body and reinforcing bar concealed beam and by the unyielding performance objective design guarantee Lateral Resistant System of middle shake
Anti-earthquake ductility performance under shaking greatly in, provides enough lateral resistant abilities for overall structure and guarantees support column 3 as no side
Move gravity column.To guarantee concrete wall 1 to effective lateral support of all support columns 3, girderless floor 2 is designed as integral rigidity
Actuating system carries out system design to the horizontal Path of Force Transfer of superstructure, it is ensured that structure shaken greatly under globality and power transmission can
By property.
Support column 3 of the present invention as distributed swing column arrangement according to vertically (dead load+live load) load
Size and building use space determine that axial compression ratio can use 0.5-1.0, optimum value 0.8.Slenderness ratio control is 150 hereinafter, not holding
Carry on a shoulder pole integrally-built horizontal loading (earthquake load+wind load).Concrete side is preferably arranged as tube structure to shear wall 1.It holds
Carry on a shoulder pole the horizontal direction load (earthquake load+wind load) of entire infrastructure.It can use 200-700 millimeters thick according to the height wall 1 of building
Degree, the reinforcing bar configuration of wall 1 should execute the existing related specification requirement of country, at least two-layer two-way reinforcement, top bottom structure without
It need to be handled, for conventional shear wall structure system construction.2 structure of girderless floor is normal floor, can configure double-layer double-direction
Reinforcing bar plays the role of transmitting horizontal loading, and controls the tensile stress of floorslab concrete less than zero.
Free profile of the present invention waves structure of the support column 3+ concrete side to stress balance wall 1, is suitable for exhausted
The multistory large spaces building not high to span demand can realize that relatively free pillar is laid out, pillar according to the needs in space
The slenderness ratio of superelevation reduces the visual impact to space permeability.In building all columns be upper and lower side it is hinged wave support
Column 3 does not set beam between swing column and floor, building clear height is reduced while guaranteeing to build smooth architectural appearance.It can fill simultaneously
Divide and utilize building escalator Core Walls Structure shear wall structure, is i.e. the part of wall 1 is arranged in building escalator as far as possible, and other places are left for
Building function can effectively improve the utilization efficiency of building；When escalator lateral wall in building is set as tubular construction, it can also increase anti-side
Rigidity.
The present invention undertakes vertical force by freely thin swing column, and concrete wall undertakes two points of stress models of horizontal force,
On the one hand the structure height for avoiding large span architecture large scale, on the other hand needs to form adaptability according to building with free buttress shaft
Spatial model, the slenderness ratio of super large also makes space more penetrating, efficiently solves structure in multistory large spaces large span architecture
Height is big, the low problem of space service efficiency；In addition, the present invention overcomes pillars in multistory large spaces framed building in lateral resisting
It is required that lower pillar section is limited, the problem of space permeability deficiency；And multistory large spaces framed building center pillar net regularization cloth
It sets, the limited problem of spatial model.Concrete wall solves the horizontal force of building while providing vertical space
Problem, flexible topology while free buttress shaft solves Gravity Problem to building bring possibility, two kinds of difference systems it is compound both
Have structured reasonability, provide system guarantee to the innovation of architectural mode, has for the Spacial innovation of building important
Realistic price.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
