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>
