## 1.Introduction

Hello and welcome to another structure analysis tutorial .

In the last tutorial , we create our free account and first project.

In this tutorial , we will use this powerful Truss and Roof calculator to create our first Truss structure.

In the end of this tutorial , you will be able to design and calculate any truss structure and get all the analysis

You can check out the full project in this link .So let's start it

## 2.Design Structure

### Nodes

Define nodes with these coordinates

### Bars

Define bars with these start and end nodes

### Supports

Apply support pinned to node 1 and roller x to node 4

### Rleases

All beams are articulated in both side.So,apply release P-P to all beams using the shortcut: *

### Materials

Define material m1 with Young Modulus equal to 210000 megapascal

### Sections

Define a square hollow section s1 with 7 centimeter side and half centimeter thickness with m1 material you just create

apply section s1 to all beams using the shortcut: *

## 3.Apply Loads

### Point Loads

Define Point Loads :

- P with magnitude of -36 kilonewton in direction of Z
- Q with magnitude of -18 kilonewton in direction of Z

Apply Point Load P to node 1 and Point Load Q to nodes 2 and 3

## 4.Calculate And Get Results

### Calculate

Verify your structure and click solve to start calculate

### Reactions

the reactions of the structure equal to :

- 54 kilonewton in direction of Z in node 1
- 36 kilonewton in direction of Z in node 4

### Displacements

The maximum displacement of the structure equal to :

- -1.017 millimetre in direction of X in node 4
- -2.267 millimetre in direction of Z in node 2

### Detailed Analysis

The maximum shear force of the structure equal to -62.776 kilonewton in all beam 6

the length of beam 6 equal to 2.44 m and its section s1 has Area equal to 13 cm2 and Inertia(Iy) equal to 92 cm4

## 5.Conclusion:

Now you become able to design and calculate any truss structure and get all the results you need.
