History of STAAD

STAAD or (STAAD.Pro) is a structural analysis and design computer program originally

developed by Research Engineers International at orba !inda" #A in year $%%&. In late '"

Research Engineers International *as bought by +entley Systems.

An older version called Staad,III -or *indo*s is used by Io*a State niversity -or

educational purposes -or civil and structural engineers. Initially it *as used -or D/S,0indo*

system. The commercial version STAAD.Pro is one o- the most *idely used structural analysis

and design so-t*are. It supports several steel" concrete and timber design codes. It can ma1e use

o- various -orms o- analysis -rom the traditional $st order static analysis" 'nd order p,

delta analysis" geometric nonlinear analysis or a buc1ling analysis. It can also ma1e use o-

various -orms o- dynamic analysis -rom modal e2traction to time history and response spectrum

analysis. In recent years it has become part o- integrated structural analysis and design solutions

mainly using an e2posed API called /penSTAAD to access and drive the program using a 3+

macro system included in the application or other by including /penSTAAD -unctionality inapplications that themselves include suitable programmable macro systems. Additionally

STAAD.Pro has added direct lin1s to applications such as RA4 #onnection and

STAAD.5oundation to provide engineers *or1ing *ith those applications *hich handle design

post processing not handled by STAAD.Pro itsel-. Another -orm o- integration supported by

STAAD.Pro is the analysis schema o- the #I4steel Integration Standard" version ' commonly

1no*n as #IS6' and used by a number modelling and analysis applications.

STAAD #vervie'

A STR#TRE can be de-ined as an assemblage o- elements. STAAD is capable o- analy=ing and designing structures consisting o- both -rame" and 5inite elements. Almost any

type o- structure can be analy=ed by STAAD.

5rame elements K +eam elements K ' nodes

5inite elements K $.) Plate K or @ nodes

'.) Solid K @ to ? nodes

In case o- STAAD

:ode becomes oint it has a number and 2y= coordinates

+eam becomes 4ember it has a number and nodes at its ends

Plate becomes Element it has a number and node at its corners

TPES /5 STR#TRE

A TRSS structure consists o- truss members *hich can have only a2ial member -orces

and no bending in the members. A P!A:E structure is bound by a global J, coordinate system

*ith loads in the same plane. A SPA#E structure" *hich is a three dimensional -ramed structure

*ith loads applied in any plane" is the most general. A 5!//R structure is a t*o or three

dimensional structure having no hori=ontal (global J or L) movement o- the structure M5J" 5L C

4 are restrained at every 8ointN. The -loor -raming (in global J,L plane) o- a building is an

ideal e2ample o- a 5!//R structure. #olumns can also be modelled *ith the -loor in a 5!//R

structure as long as the structure has no hori=ontal loading. I- there is any hori=ontal load" it must be analy=ed as a SPA#E structure.

There are basically methods o- generating a modelO Snap node method" #oordinate

method and #opy paste method. /ut o- these three methods most commonly used is copy paste

method. +y using these three methods a structure o- any geometry can be created STAAD.Pro
