3. Methodology
4. Results and Discussion
- The material of the connection (plate, stiffeners, double-reinforcement plates and continuity plates) was the same as the material used for the beam; since Revit does not include this parameter in the element, this information cannot be imported to Dynamo.
- The information of some components of the connection cannot be transferred from Revit to Dynamo because they do not interact directly; that is, there is no node that allows the components of the connection to be brought into Dynamo, so it was decided to manually model the plates in Dynamo.
- It was necessary to add mechanical parameters for the beams and columns that were not included within the families of these elements, such as the plastic modulus of the section (Z) for both the beam and the column and the distance from the end face of the member flange to the tip of the fillet in the web (K) of the column.
- For purposes of generative design, the design of the plate reinforcements, such as continuity plates, stiffeners, and double-reinforcement plates, was not considered.
4.1. Design and Development of the Solution
- vertical distance between the outer end bolts and the edge of the end plate
- vertical distance between the inner and outer bolt rows
- vertical distance from the outside of the tension flange to the nearest outside bolt row
- vertical distance from the inside of the tension flange to the nearest inside bolt row
- vertical distance between the rows of interior and exterior bolts, which for the purposes of the investigation will be equal to the variable b
- horizontal distance between the outer bolts and the edge of the end plate
- horizontal distance between bolts
- bolt diameter
- plate thickness
- : number of connection bolts in the compression flange, i.e., 8 for the purposes of this study;
- nominal strength of the bolts;
- gross bolt area in , represented in Equation (2).
- ø: resistance factor, i.e., 0.9 for the purposes of this study;
- shear force at the center of the plastic hinge.
