一、 结构断缝(图中蓝色线) 断开2道缝优点：避开高层超限，节约造价

1. Structural breaks (blue line in the figure) <br> Disconnect two seams <br>Advantages: Avoid high-rise overruns, save <br>construction cost . Adjust the position according to the building function. <br>Follow-up to be discussed: single column overhang, corresponding staircase 2. Corridor may need to be adjusted in position and width <br>2. Structure column movement and adjustment position <br>1. Increased column position: magenta columns in the picture <br>Advantages: <br>A. Avoid overhanging staircase (shock resistance is not allowed) <br>B. Avoid too large Cantilever, unfavorable earthquake resistance, increase the cost, such as <br> open reading space in the lower right corner <br> large cantilever on the roof of the greenhouse garden  large cantilever in the <br>reading area of ​​the landscape, steel columns with small cross-sectional dimensions can be used, and the impact on the building effect is small (4F~6F ) <br>2. The blue color is the new column (the cross is the original column position): mobile <br>advantages: <br>A. Move the column net with the roof shape of the greenhouse garden, at the same time, it is more conducive to the transparency of the lighting roof <br>B. Cooperate with the 2F facade adjustment column Allow the outer skin of the building to cover the pillars. <br>3. Supplementary structural slab area (red shaded area) <br>Advantages: <br>A. Continuous slabs are conducive to horizontal seismic force transfer (3F) <br>B. Supplementary structural slabs in the landscape reading area are conducive to earthquake resistance of structural frame beams , or prone to frame beam shear twist brittle failure (6F, 7F) <br>Fourth, the atrium entrance position move (in green entrance area) <br>A. Option one: the atrium entrance partial move to ensure maximum cantilever beam does not exceed 4m, <br>to Take 2F as an example, the rest is similar to <br>scheme 2: Take the frame beam as the separation area, take 4F as an example, and the rest is similar. <br><br>5. Suggestions <br>1. The center of the structural column is aligned with the intersection of the grid, try not to have too much error<br>2. Please provide the floor height of the remaining floors except the first and second floors, as well as the floor elevation of the building. <br>3. The cad drawings have not reflected the contour of the equipment roof. <br>4. The floor of the landscape reading area is recommended to use light floor, such as wooden floor, reduce Structural self-weight <br>5. Because there are many openings in the library floor, secondary beams are required to separate the plates. It is not recommended to use the slab column-shear wall or frame column + frame beam (without secondary beam) structure. It is recommended to use the frame structure ( Primary and secondary beam system) <br>6. There are steps hanging in the atrium area in the lower left corner, there are no floors around, please update the cad plan

First, structural breaks (blue lines in the figure)<br>Break 2 seams<br>Pros: Avoid high-level overlimits and save cost<br> Positions can be adjusted appropriately to the building function<br>Follow-up: single-pillar suspension, the corresponding stairwell, corridor may need to adjust the position and width<br>Second, structural column movement and adjustment of position<br>1. Increase the position: the magenta column in the figure<br>Advantages:<br>A. Avoid hanging stairwells (seismic ally not allowed)<br>B. Avoid excessive overhang, adverse earthquake resistance, increased costs, e.g.<br>Open reading space in the lower right corner<br>Greenhouse garden roof hanging<br>Large suspension of landscape reading area, steel columns with small cross-sectional sizes can be used, with a small impact on the building effect (4F to 6F)<br>2. Cyan for new column (fork is original): move<br>Advantages:<br>A. Move the column net in conjunction with the roof shape of the greenhouse garden, while being more conducive to the permeability of the roof of the light<br>B. Adjust the post position with the facade of 2F and allow the exterior of the building to cover the columns<br>Third, supplementthe structure plate area (red shaded area)<br>Advantages:<br>A. Continuous flooring for horizontal seismic force transfer (3F)<br>B. Landscape reading area supplement structure floor, conducive to structural frame beam slab earthquake resistance, otherwise the frame beam is prone to shearing and brittle damage (6F, 7F)<br>Fourth, the atrium hole position moved (in the green hole hole area)<br>A. Option 1: The opening of the atrium moves in a partial direction to ensure that the maximum suspension of the beam does not exceed 4m,<br>Take 2F as an example, the rest is similar<br>Scenario 2: Frame beam as a separate dissonned area to 4F for example, the rest similar<br><br>V. Recommendations<br>1. Structural column center is aligned with the axis mesh intersection point, try not to have too much error<br>2. Please provide the height of the remaining floors in addition to the first and second floors, as well as the height of the floors of the building<br>3. Cad drawings do not reflect the outline of the roof of the equipment<br>4. The use of lightweight slabs, such as wooden slabs, is recommended for flooring in landscape reading areas to reduce structural self-weight<br>5. Because the library floor opens more holes, the need for subbeam separation plate, it is not recommended to use the column-shear wall or frame column and frame beam (no subbeam) structural form, it is recommended to use the frame structure (main subbeam system)<br>6. The atrium area in the lower left corner has a slab suspension and there are no floors around, please update the cad floor plan

1、 Structural fracture (blue line in the figure)<br>Disconnect 2 seams<br>Advantages: avoid high-rise overrun and save cost<br>The location can be adjusted according to the building function<br>Later to be discussed: in case of single column cantilever, the corresponding stairwell and corridor may need to be adjusted in position and width<br>2、 Structural column movement and adjustment position<br>1. Add column position: magenta column in the figure<br>advantage:<br>A. Avoid cantilevered staircases (seismic not allowed)<br>B. Avoid excessive overhang, seismic disadvantage and increase cost, such as<br>Open reading space in the lower right corner<br>Greenhouse garden roof overhang<br>In the landscape reading area, large cantilever can be used, and steel columns with small section size can have little impact on the architectural effect (4F ~ 6F)<br>2. Cyan is the new column (cross is the original column position): move<br>advantage:<br>A. Move the column net according to the roof shape of the greenhouse garden, which is more conducive to the permeability of the daylighting roof<br>B. Coordinate with 2F facade to adjust the column position, and let the exterior of the building cover the column<br>3、 Supplementary structural slab area (red shaded area)<br>advantage:<br>A. Continuous floor slab is conducive to horizontal seismic force transmission (3f)<br>B. The landscape reading area complements the structural floor slab, which is conducive to the seismic resistance of the structural frame beam, otherwise the frame beam is prone to shear torsional brittle failure (6F, 7F)<br>4、 Move the location of atrium opening (green hole area in the figure)<br>A. Scheme 1: the entrance of the atrium is shifted to ensure that the maximum overhang of the beam does not exceed 4m,<br>Take 2F for example, the rest are similar<br>Scheme II: take frame beam as the separation area, take 4f as an example, and the rest are similar<br>5、 Recommendations<br>1. Align the intersection of structural column center and grid, and try not to have too large error<br>2. Please provide the floor height of other floors except the first floor and the second floor, as well as the floor elevation of the building<br>3. The CAD drawing does not reflect the outline of the equipment roof<br>4. It is recommended to use light floor in the landscape reading area, such as wooden floor, to reduce the self weight of the structure<br>5. Because there are many openings in the library floor, the secondary beam is needed to separate the plates. It is not recommended to adopt the structural form of plate column shear wall or frame column + frame beam (without secondary beam). It is recommended to adopt the frame structure (primary and secondary beam system)<br>6. Steps are suspended in the atrium area at the lower left corner, and there is no floor around. Please update the CAD plan<br>
