Thesis (MScEng)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: AP230 of STEP is an application protocol for structural steel-framed buildings. Product
data relating to steel structures is represented in a model that captures analysis, design
and manufacturing views.
The information requirements described in AP230 were analysed with the purpose of
identifying a subset of entities that are essential for the description of simple industrial
steel frames with the view to being able to describe the structural concept, and to perform
the structural analysis and design of such structures.
Having identified the essential entities, a relational database model for these entities was
developed. Planning, analysis and design applications will use the database to
collaboratively exchange data relating to the structure. The comprehensiveness of the
database model was investigated by mapping a simple industrial frame to the database
model.
Access to the database is provided by a set of classes called the database representative
classes. The data-representatives are instances that have the same selection identifiers
and attributes as corresponding information units in the database. The datarepresentatives'
primary tasks are to store themselves in the database and to retrieve their
state from the database.
A graphical user interface application, programmed in Java, used for the description of
the structural concept with the capacity of storing the concept in the database and
retrieving it again through the use of the database representative classes was also created
as part of this project. / AFRIKAANSE OPSOMMING: AP230 van STEP is 'n toepassingsprotokol wat staal raamwerke beskryf. Die produkdata
ter beskrywing van staal strukture word saamgevat in 'n model wat analise, ontwerp en
vervaardigings oogmerke in aanmerking neem.
Die informasie vereistes, soos beskryf in AP230, is geanaliseer om 'n subset van entiteite
te identifiseer wat noodsaaklik is vir die beskrywing van 'n eenvoudige
nywerheidsstruktuur om die strukturele konsep te beskryf en om die struktuur te analiseer
en te ontwerp.
Nadat die essensiële entiteite geïdentifiseer is, is 'n relasionele databasismodel van die
entiteite geskep. Beplanning, analise en ontwerptoepassings maak van die databasis
gebruik om kollaboratief data oor strukture uit te ruil. Die omvattenheid van die
databasis-model is ondersoek deur 'n eenvoudige nywerheidsstruktuur daarop afte beeld. Toegang tot die databasis word verskaf deur 'n groep Java klasse wat bekend staan as die
verteenwoordigende databasis klasse. Hierdie databasis-verteenwoordigers is instansies
met dieselfde identifikasie eienskappe as die ooreenkomstige informasie eenhede in die
databasis. Die hoofdoel van die databasis-verteenwoordigers is om hulself in die
databasis te stoor asook om hul rang weer vanuit die databasis te verkry.
'n Grafiese gebruikerskoppelvlak, geprogrammeer in Java, is ontwikkel. Die koppelvlak
word gebruik om die strukturele konsep te beskryf, dit te stoor na die databasis en om dit
weer, met behulp van die databasis-verteenwoordigers, uit die databasis te haal.
