SAP 2000 Tutorial Session Notes - Professor Buyukozturk

1.051 Structural Engineering Design Prof. Oral Buyukozturk Fall 2003 SAP 2000 Tutorial Session Notes This tutorial provides the basic steps of performing a frame analysis using SAP 2000. It is based on the design project example shown below, the complete solution of which is provided as a handout. 16@21' 26' 34' 26' 20' 5@13' 15' Results of Preliminary Analysis: Slab thickness: 9 in Beam dimensions: 14”x31” Exterior columns: 14”x18” Interior columns: 16”x22” Loads: Exterior beams: LL=0.72 kips/ft DL=1.85 kips/ft Interior beams: LL=0.83 kips/ft DL=2.10 kips/ft Wind and Earthquake loads are specified in the appendix. Only earthquake loads are considered. The frame is solved in the short direction only since this direction is more critical. 1.051 Structural Engineering Design Prof. Oral Buyukozturk Fall 2003 Analysis Steps 1. Generate the frame geometry from analysis templates. Menu: File > New model from template Result Note: make sure that proper units are selected (shown

in the lower right corner) 1.051 Structural Engineering Design Prof. Oral Buyukozturk Fall 2003 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: 1.051 Structural Engineering Design Prof. Oral Buyukozturk Fall 2003 2. Set Boundary Conditions The default boundary condition in the template is simple supports at the bottom. We need to change those to fixed supports. After selecting these joints, one can either use the menu: Assign > Joint > Restraints, or the quick menu button at the top (Restraints is the first one). 3.
