Getting Started: Building Your First Model

Before you can analyze anything, you need a structural model. The process is linear: definite thee geometry, assign materials andd sections, applicy supports andd loads, then run the analysis. Below is a step-by-step walktrimagh for a simple steel frame.

1. Stworzenie New Model andSet Up Grids

2. Draw the Structural Members

With the grid in place, use the insignal 1; direction 1; FLT: 0 indis3; Draw Member present 1; Ig1; FLT: 1 consecui3; Iglol (icon simpligg a beem) from the toolbar. Click on twos nodes two create a prostt member. Draw columns vertically betuween consecutiva foop nodes, and beams horizontally along thee grid lines. You can draw multiple members by conting tlo click - press 1; FLT: 2 addis3AM 3Esc; Esc; FLT 1; 3D: 3r; ob; or trick-clisk the commisd.

For a complete frame, draw all columns on every story, then draw beams on each floor level. Risa automatically asigns a default steel section (np., W12x26) to new members, but you can change these later.

You can also assign supports to individual nodes by selecting them. For a 2D frame, ensure out-of-plane degrees are condived to prevent instability.

Amplying Loads

With geometrie and supports ready, the next step is to define thee forces that thee structure mutt resist. Risa supports all contexn load types andd load combinations per ASCE 7 or tell building codes.
