Assign member and joint loads for each load case Select members or joints with similar load type and values, and assign proper loading using quick menu buttons or below menu items. New load cases can be added from the below menu item. Dead load (DL), live load (LL), and earthquake loading (E) are considered in this example. Define static load cases Define the type of load cases considered in design. After assignment of member sections 2D Extruded viewĦ 5. After assigning the sections, 2D/3D Extruded shape of the members can be seen from Menu: View > Set Elements > Extruded shape or using the shortcut menu button.
Define and assign frame sections Define the beam, exterior column, and interior column sections Menu: Define > Frame Sections > Add Rectangular Note: Don t forget to change the units to kips-in before specifying member dimensions beam exterior column interior column After the member sections are defined, select members with common sections and assign the respective section from menu: Assign > Frame > Sections. Define Material Properties f = 4 ksi = 576 ksf ' c E = 3605 ksi = ksf c f = 60 ksi = 8640 ksf y E = ksi = ksf y Menu: Define > Materials > Concĥ 4. After selecting these joints, one can either use the menu: Assign > Joint > Restraints, or the quick menu button at the top the first one). We need to change those to fixed supports. Set Boundary Conditions The default boundary condition in the template is simple supports at the bottom. Menu: File > New model from template Result Note: make sure that proper units are selected (shown in the lower right corner)ģ Since we chose the common floor heights and bay spans, we need to move the grids Menu: Draw > Edit Grids X-grids before and after Before After Z-grids before and after Before After Result:Ĥ 2. Generate the frame geometry from analysis templates. The frame is solved in the short direction only since this direction is more critical.Ģ Analysis Steps 1. 20' 26' 34' 26' 15' Results of Preliminary Analysis: Slab thickness: 9 in Beam dimensions: 14 x31 Exterior columns: 14 x18 Interior columns: 16 x22 Loads: Exterior beams: Interior beams: LL=0.72 kips/ft DL=1.85 kips/ft LL=0.83 kips/ft DL=2.10 kips/ft Wind and Earthquake loads are specified in the appendix. Tutorial Session Notes This tutorial provides the basic steps of performing a frame analysis using SAP It is based on the design project example shown below, the complete solution of which is provided as a handout.
