Under beam, concrete external wall panel is located at immediately below structural beams, makes structural beams and concrete external wall panel under beam same flat Face, under beam, the clear span of concrete external wall panel width ratio structural beams is little, to ensure structure lateral deformation capacity.By specification JGJ3 and JGJ99, the elastic displacement angle limit value of concrete frame structure is 1/550, and plastic displacement angle limit value is 1/50;Steel structure frame is tied The elastic displacement angle limit value of structure is 1/250, and plastic displacement angle limit value is 1/70;Concrete frame-shear wall structure or steel framework- Concrete shear wall structure elastic displacement angle limit value 1/800, plastic displacement angle limit value is 1/100;The coagulation of floor height 2.9m-4.5m Soil framed building, inter-storey elastic displacement limit value is 5.3-8.2mm, and plasticity relative storey displacement limit value is 58-90mm;Steel framed building, Inter-storey elastic displacement limit value is 11.6-18mm, and plasticity relative storey displacement limit value is 41-64mm;And frame-shear structure building, elastic displacement Angle limit value is 29-45mm at 3.7-5.7mm, interlayer plastic displacement limit value.With reference to agent structure Deflection Bound and execution conditions, enter The perpendicular piece width design of row.Consider that perpendicular piece is excessive, be unfavorable for sealing gluing, during design, the metope of concrete external wall panel under beam Between the perpendicular piece of segmentation leave and take the width of 20-25mm the most in advance, this design be sufficient to guarantee set up defences geological process time, agent structure bullet Property deformation do not affected by concrete external wall panel under beam.

Hereinafter using Ansys finite element program, concrete and steel plate are simulated in bulk body unit, and (three-dimensional 6 bodies 20 save Point), use C40 concrete strength and Q345 steel parameter, the component of structural beams wall one weight external wall plate is carried out flexibility analysis, make Firmly take from certain 26 layer concrete frame-shear structure residential housing overall calculation and analyze corresponding internal force.This building is positioned at earthquake to accelerate Degree 0.10g area, seismic behavior is two grades.Take a certain single Pin single span framework of monolayer and carry out modeling, on post and in structural beams All having vertical uniform load q, capital has horizontal loads, this calculating mainly checking, concrete exterior wall panel stiffness under considering beam When affecting, under structural beams, post and beam, the internal force between each component of concrete external wall panel distributes.Result of calculation is as follows: this list Pin single span The frame model of structural beams wall one weight external wall plate, under the geological process considering 7 degree of fortification intensities, maximum horizontal sidesway is 0.446mm, and now concrete beam end beam soffit stress is maximum, for reaching cracking at first.Software analysis result illustrates: framework side The width of the 20-25mm that shifting amount is reserved much smaller than perpendicular piece.Concrete external wall panel, not shadow under beam in structural beams wall integrated unit Ring the displacement of framework sidesway, maintain strong column and weak beam conceptual design requirement.

Consider to reduce further concrete external wall panel under beam and, on beam-ends section rigidity and the impact of frame deformation, use framework The design concept that the Su Jiao district section rigidity of beam-ends should not be strengthened, the reinforcement detailing practice is the vertical steel of concrete external wall panel under beam Muscle being set in stretching into structural beams: along centre, structural beams direction is close and two ends are sparse, and beam end portion leaves certain length It is not connected to or Weak link with concrete external wall panel under beam.When calculating simulation, beam-ends position sets not with concrete external wall panel under beam Connect horizontal joint, concrete external wall panel and the Connection Release of beam-ends position under beam, ibid, analysis result is as follows for stress model: this Time maximum horizontal sidesway slightly add greatly 0.463mm, now under beam, concrete external wall panel is for reaching cracking at first, next to that structure Beam, is finally post.Framework amount of side-shift typically reserves width much smaller than perpendicular piece.Concrete under beam in structural beams wall integrated unit Side fascia, does not affect the displacement of framework sidesway.Staying seam under beam-ends and beam between concrete external wall panel, frame deformation ability strengthens, structure The bearing capacity of beam still can remain less than the bearing capacity of post component, maintains the version i.e. framework that structure beam and column is constituted The strong column and weak beam characteristic of structural system.

Under kindred circumstances, for section steel beam component in structural beams wall integrated unit, continue to use Ansys finite element software Simulation calculates, and loads result of calculation as follows: the section steel beam two ends section of stretching out without concrete parcel is passed through in connecting plate and post Shaped steel by welding and bolt carry out just connecing in succession, it is considered to same seismic action combination operating mode, described software analysis result Display, now maximum horizontal sidesway 0.749mm, and the stress of section steel beam is still greater than steel column, framework amount of side-shift is much smaller than perpendicular piece General reserved 20mm width.Result of calculation illustrates, concrete external wall panel, not shadow under the beam in section steel beam wall integral wall board member Ring the displacement of framework sidesway, and strong column and weak beam concept can be kept.

As only considered vertical uniform load q, when designing without seismic action combination.Result of calculation is as follows: only vertical uniform load q Time, girder span middle section likely total cross-section pressurized, tensile region, cross section is transferred to concrete external wall panel span centre hypodermis under beam.Therefore, In designing without seismic combination, it is considered to all should be able to across tension arrangement of reinforcement and isolated beam span centre arrangement of reinforcement in the cross section of structural beams wall integral member Resist the Moment under this operating mode, and avoid concrete external wall panel hypodermis premature rupture under beam.Structural beams wall integral member The acting force arm of cross section tension reinforcement is relatively big, and under beam, concrete external wall panel spaning middle section arrangement of reinforcement demand is relatively small, this area skill Art personnel arrange tension reinforcement without difficulty.
