FEA Structural Analysis

1)Answers:

A)Aim:Write the steps involved to upload a .std file through web mail?

Introduction :

STAAD pro ( Structural Analysis and Deign program is the abbrivation for the STAAD it is the connected version new version used to analize the RCC structure and steel structure by using this software )
It Include the GUI Graphic User Interface for Visualization and contains various design codes

Procedure :

Open the software Staad pro in the landing page
Click on share icon in
Click on send mail
Browse the file you want to share
Click on send mail
Ensure that you are sign in

B) The type of materials used in staad pro

C) If you want to get the pictures in an external file ( like a word file, excel file, MsPaint etc.) go to the menu option Edit > Copy Picture, open the application you want and do a paste in there. Files saved through Take Picture option are not directly saved in common picture formats like bmp, jpg, png.

Press tab,the navigate arrow key to edit menu,then click on take picture

D) There are three methods of creating the structure data:

Using the STAAD.Pro Physical Modeler interface,
Using the traditional STAAD.Pro analytical modeling interface,
Using the command line

The physical model is used to draw structural elements as they are physically constructed. The program will then decompose this into an analytical modeling which is passed to the STAAD.Pro analysis and design engine when you run your model.

The analytical model is a finite element model of the structure which is typically processed directly by the analysis and design engine.

The command input file is a text file which contains the data for your structural model. This file consists of simple English language-like commands. This file is created for you behind the scenes for you when you model your structure using either the physical modeler interface or the analytical model interface.

In STAAD.Pro Physical Modeler, the general order of operations is that you first select physical objects and then assign properties or perform some operation on the selection.

This differs from STAAD.Pro, where there are many tasks in which you select the operation, property, or specification first and then assign that to some list of model objects.

Comparison of Order of Operations

In this example, the operation of assigning profile sections to a selected set of beams is compared.

STAAD.Pro Physical Modeler interface	STAAD.Pro analytical modeling interface
Select the members which all have the same section.	Add the profile you want to use from the Section Database.
Select the Section tool in the Assign properties group on the Member ribbon tab.	Select the member property in the Properties dialog.
Select the profile to use and click OK.	Use the cursor to click on members with this property

2)Answers:

A)The program contains a number of parameters that are needed to perform design as per IS 13920 2016. It accepts all parameters that are needed to perform design as per IS:456. Over and above it has some other parameters that are required only when designed is performed as per IS:13920 2016. Default parameter values have been selected such that they are frequently used numbers for conventional design requirements.

Parameter Name	Default Value	Description
EUDL	None	Equivalent u.d.l on span of the beam. This load value must be the unfactored load on span. During design the load value is multiplied by a factor 1.2. If no u.d.l is defined factored shear force due to gravity load on span will be taken as zero. No elastic or plastic moment will be calculated. Shear design will be performed based on analysis result.(Refer note)
BRACING	0.0	Beam Design 1.0 = the effect of axial force will be taken into account for beam design. Column Design: Correspond to the terms "Braced" and "Unbraced" described in Notes 1, 2, and 3 of Clause 39.7.1 of IS456:2000 1.0 = the column is unbraced about major axis. 2.0 = the column is unbraced about minor axis. 3.0 = the column is unbraced about both axis
ELY	1.0	Ratio of effective length to actual length of column about minor axis.
ELZ	1.0	Ratio of effective length to actual length of column about major axis.
EUDL	None	Equivalent u.d.l on span of the beam. This load value must be the unfactored load on span. During design the load value is multiplied by a factor 1.2. If no u.d.l is defined factored shear force due to gravity load on span will be taken as zero. No elastic or plastic moment will be calculated. Shear design will be performed based on analysis result
FYMAIN	415 N/mm2	Yield Stress for main reinforcing steel.
FYSEC	415 N/mm2	Yield Stress for secondary reinforcing steel.

C)To navigating the model view

The view window contains a unique control device called the Rotation Gizmo which allows you to select set view orientations or to orient the model in the view about the global axes.
Click the Rotation Gizmo to display preset views. Click the Invert icon to display the reverse of these views.

Click and drag on the Rotation Gizmo axes to rotate the view about that global axis.
Click on the zoom controls to zoom in or out of parts of the model. Click-and-drag the middle mouse button (i.e., scroll wheel) to pan the view.
Click on the Perspective control to display the perspective switch and slider.

D)Explain the procedure to define a “Simply Supported” condition in STAAD Pro

Ans :

Go to the support command in the tool palet command
Click on create support command
There we can get option like fixed support , pin support , Fixed but
Enforced but support
Cable support
Inclined support

E)Name any five topics that you will include while creating DBR.

DBR Design basis report
To take up a project from the scrach to the end this is need
To specify the data and compile data recived and analysis and design of structural element
It contains the assumption and specification to develop the project
It will help to avoid the scope and the creep that can derail the projec schedule and lead to budget overness
Contains the general Column drawing
Contains the projec planning

It also contains other parts also such as:

Length:The body of the report should be no more than ten double-spaced pages. Detailed design work, drawings, diagrams, engineering analyses, vendor part descriptions (e.g., gears, bearings), parts lists, and references should be referred to in the body of the report and then included as attachments.

Purpose of the Report:The purpose of the report is to describe all aspects of your mechanical design project in a concise and thorough manner.

Audience:Assume that your report will be read by your supervisor (D. Walczyk) and other design and manufacturing engineers working on this project.

Organization:

Title Page:Include the title of the report, your name, the class, and date of submission.
Executive Summary:Summarize what was asked for, what you accomplished and how it was accomplished. Include your main results and conclusions. Put this section first in the report but write it last. The summary should stand alone from the rest of the report. Limit it to one page (double-spaced) or less.
The Problem:Summarize the details of your chosen design project. In addition to the original problem description, include any additional tasks that you have decided to accomplish.
