Under beam, concrete external wall panel is located at immediately below structural beams, makes structural beams with concrete external wall panel under beam in the same plane, and 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;The elastic displacement angle limit value of steel structure frame 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 concrete frame building of floor height 2.9m-4.5m, inter-storey elastic displacement limit value is 5.3-8.2mm, and plasticity interlayer limit displacement value is 58-90mm;Steel framed building, inter-storey elastic displacement limit value is 11.6-18mm, and plasticity interlayer limit displacement value is 41-64mm;And frame-shear structure building, elastic displacement angle limit value is at 3.7-5.7mm, and interlayer plastic displacement limit value is 29-45mm.With reference to agent structure Deflection Bound and execution conditions, carry out perpendicular piece width design.Consider that perpendicular piece is excessive, being unfavorable for sealing gluing, during design, under beam, the perpendicular piece of splitting between the metope of concrete external wall panel generally leaves and takes the width of 20-25mm in advance, this design foot is when geological process is set up defences in guarantee, and agent structure elastic deformation is not affected by concrete external wall panel under beam.

Hereinafter adopt Ansys finite element program, concrete and steel plate are simulated in bulk body unit (three-dimensional 6 body 20 nodes), adopts C40 concrete strength and Q345 steel parameter, the component of beam wall one weight external wall plate of section steel beam is carried out flexibility analysis.For making comparisons with beams of concrete wall one framework, active force takes from certain 26 layer concrete frame-shear structure residential housing corresponding internal force of overall calculation analysis.This building is positioned at seismic acceleration 0.10g area, and seismic behavior is two grades.First take a certain single Pin single span concrete frame-type in monolayer and carry out modeling, post there is vertical uniform load q with Liang Shangjun, capital has horizontal loads, this calculating mainly checking is under considering beam during concrete external wall panel stiffness effect, and under beam, post and beam, the internal force between each component of concrete external wall panel distributes.Result of calculation is as follows: the frame model of beam wall one weight external wall plate of the section steel beam of this list Pin single span, and 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.Illustrate through this software analysis result: the width of the 20-25mm that framework amount of side-shift is reserved much smaller than perpendicular piece.Concrete external wall panel under beam in beam wall integrated unit, does not affect the displacement of framework sidesway, maintains strong column and weak beam conceptual design requirement.

Consider that perpendicular piece is excessive, being unfavorable for sealing gluing, during design, under beam, the perpendicular piece of splitting between the metope of concrete external wall panel generally leaves and takes the width of 20-25mm in advance, this design foot is when geological process is set up defences in guarantee, and agent structure elastic deformation is not affected by concrete external wall panel under beam.

Hereinafter adopt Ansys finite element program, concrete and steel plate are simulated in bulk body unit (three-dimensional 6 body 20 nodes), adopt C40 concrete strength and Q345 steel parameter, the component of beam wall one weight external wall plate of section steel beam is carried out flexibility analysis, and active force takes from certain 26 layer concrete frame-shear structure residential housing corresponding internal force of overall calculation analysis.This building is positioned at seismic acceleration 0.10g area, and seismic behavior is two grades.Take a certain single Pin single span framework of monolayer and carry out modeling, on post and all have vertical uniform load q in structural beams, capital has horizontal loads, and this calculatings mainly is verified, under considering beam during concrete external wall panel stiffness effect, under structural beams, post and beam, the internal force between each component of concrete external wall panel distributes.Result of calculation is as follows: the frame model of structural beams wall one weight external wall plate of this list Pin single span, and 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: the width of the 20-25mm that framework amount of side-shift is reserved much smaller than perpendicular piece.Concrete external wall panel under beam in structural beams wall integrated unit, does not affect the displacement of framework sidesway, maintains strong column and weak beam conceptual design requirement.When under beam-ends position and beam, concrete external wall panel sets and is not connected to horizontal joint, the Connection Release of concrete external wall panel and beam-ends position under beam, now maximum horizontal sidesway slightly adds greatly 0.463mm. and illustrates that beam-ends arranges Weak link or is not connected to, and increases further the deformability of frame structure.

For component in the beam wall integrated unit of section steel beam, namely pass through with the shaped steel in steel column or profile steel concrete column to weld without the section steel beam two ends section of stretching out of concrete parcel, connecting plate and bolt carries out just connecing in succession.Consider same geological process, adopt Ansys finite element software to carry out another simulation to calculate, loading result of calculation is as follows: described software analysis result shows, now framework amount of side-shift maximum horizontal sidesway 0.749mm, and the stress of section steel beam is still greater than the steel column in post, the 20mm width that framework amount of side-shift is generally reserved much smaller than perpendicular piece.Result of calculation illustrates, concrete external wall panel under the beam in section steel beam wall integral wall board member, does not affect the displacement of framework sidesway, and can keep strong column and weak beam concept.

As only considered vertical uniform load q, when designing without seismic action combination.Result of calculation shows: only during vertical uniform load q, girder span middle section likely total cross-section pressurized, and tensile region, cross section is likely to be transferred under beam concrete external wall panel span centre hypodermis.Therefore, in designing without seismic combination, it is considered to the Moment under this operating mode all should be able to be resisted across arrangement of reinforcement in the cross section of the beam wall one weight external wall plate component of section steel beam in tension arrangement of reinforcement with isolated beam and avoid concrete external wall panel hypodermis premature rupture under beam.The acting force arm of the cross section tension reinforcement of the beam wall one weight external wall plate component of section steel beam is relatively big, and under beam, concrete external wall panel spaning middle section arrangement of reinforcement demand is relatively small, and those skilled in the art arrange vertical reinforcement without difficulty.
