Part 2 – Problem 10: Is it allowed to use shear wall in the extension? since it is mentioned that we will be able to revise the existing building and make changes so that the shear wall connects the entire building.
The use of shear walls is allowed, however, as mentioned it should be connected to the existing building foundation (in the final version of the building).
Part 1 – Problem 13: Assuming a Seismic Design Category D, which we had calculated in the Geotechnical deliverable, Section 12.5.4 of the ASCE manual allows using Section 12.5.3a or 12.5.3b to satisfy the additional requirements of the low Seismic Design Category. The first is to design for “100% of the forces for one direction, plus 30% of the force in the perpendicular direction”. The alternative option is to have a simultaneous application of orthogonal ground motions, which would result in only 4 analyses. Since the SLC instruction asks us to analyze each direction separately do we use 12.5.3a or do we simply apply 100% of the force in only one direction?
For this deliverable, please just apply the 100% of the force in only one direction
Part 1 – Problem 11: In this part, construction details are required. Could you provide us a norm or a specific document in which we could find some regulations regarding this aspect?
There is no required format to your construction details. We are primarily interested in your thought process and reasoning behind your construction sequence. Diagrams would be a good way to convey your ideas but there is no required format.
Part 1 – Problem 12: Can we assume that non-structural elements can close in the story to calculate the floor area (i.e curtain wall)? If so, can these elements extend past the tapered building shape as the figure shows in the structural design guide of the existing and addition (i.e building elevation – south)?
Non-structural elements such as curtain walls are permitted to extend past the required footprint of the building. The plan dimensions specified in the design guide and drawings are for the purposes of constructing your numerical model. Any architectural features may extend outside of these bounds. However, please keep non-structural elements within reason (if they extend […]
Part 2 – Problem 06: According to the deliverable, ‘a thorough analysis of the structure with the addition is not required in this deliverable’. Does it mean that we need a SAP2000 model for the existing structure and another model for the additional structure, respectively, or do we need a model which contains both structures together?
For part 1 of the structural deliverable , your results should be based on your SAP/ETABS model for the existing structure only. For part 2, the addition should be incorporated into your existing model and the two components should be modeled together. For any future questions about the additional structure, analysis should be conducted based […]
