STAAD PRO ANALYSIS EXAMPLE: A Comprehensive Guide to Structural Engineering Software 'staad pro analysis design example'

In today's fast-paced construction industry, structural engineers rely on cutting-edge software like STAAD Pro to efficiently analyze and design complex structures. This article will delve into the world of STAAD Pro analysis using a real-world example - designing an R.C.C (Reinforced Concrete) building with Indian standards.

STAAD PRO: A Brief Overview

STAAD Pro is one of the leading structural engineering software programs available in the market today. It was first introduced by Computer-Aided Design and Engineering Inc., now part of Bentley Systems Incorporated, in 1984 as STAAD2D/3D (Structural Analysis And Design). The name later changed to STAADDT before finally settling down with its current moniker - STAAD Pro.

Features & Benefits

STAAD PRO offers a wide range of features and benefits that make it an indispensable tool for structural engineers worldwide. Some of these include:

1. Advanced analysis capabilities: From basic static loads to complex dynamic analyses, STAAD Pro has got you covered.

2. Comprehensive design checks: Comply with various national building codes such as ACI-318 (USA), Eurocode 8 etc., all within one platform!

3. Robust detailing tools: Generate accurate steel reinforcement drawings directly from your model for smooth construction execution.

4. Interoperability with popular CAD software like Revit, AutoCAD, etc.

Example Problem

For this article's purpose, let us consider the design of a simple three-story R.CC building having dimensions as follows:

- Total gross area = 2500 sq.m

- Floor height = 3m each floor

- Column spacing = 4.5 m x 6 m (BFT)

- Reinforcement steel reinforcement detailing based on IS : 456 - 2002 (Indian Standard for plain and reinforced concrete, code of practice)

Step-by- Step Analysis & Design Process

1. Preparing the Model:

a) Launch STAAD Pro software and create a new project.

b) Define the building's properties such as material type (RC), cross-sections etc.

2. Creating Members, Plates & Surfaces

a) Add columns, beams, walls, slabs etc., to represent the structure in 3D view using appropriate member types.

b) Assign section sizes and properties as per Indian standards for members like RCC Columns/Beams.

c) Create plates (e.g. roof slab) by drawing a closed polyline around desired area with specified thicknesses & reinforcement details if needed.

3. Applying Loads

a) Define various load combinations based on wind, snow, seismic etc., as per Indian Seismic Code IS 1893:2015 for this example.

b) Apply loads such as self-weight of members/plates alongwith distributed loads like dead & live loads over each floor plate using 'Load Case' option.

4. Analysis

a) Perform structural analysis on the loaded structure considering various factors such as gravity, lateral and torsional forces.

b) The software will then perform internal checks for stresses, deflections etc., against Indian Standards to ensure safety under different loading conditions.

5. Design Output & Reports Generation:

After successful completion of analysis step above, STAAD Pro generates detailed design output reports which include:

- Section sizes for members

- Reinforcement detailing in the form of reinforcement bars and their quantities

These outputs can then be used directly by construction teams to fabricate steel or cast concrete elements according to project specifications.

In conclusion, this article has demonstrated how STAAD Pro analysis software can efficiently support structural engineers throughout every stage - from initial design concept through finalizing detailed drawings ready for site execution. By understanding its powerful features and capabilities like those shown here with our example R.CC building modelled under Indian Codes & Standards; you too can unlock maximum potential out of this versatile toolset in your next big project!
