Tiivistelmä
This thesis work was made for Ruukki Rus, for the Russian filial of the big
Finnish company. Ruukki Rus makes projects and produce different steel
structures. However, there was a task to reduce the time spending to design
process. As standardization and unification of elements, constructions and
design solutions is one of the main ways to reduce the complexity and cost of the
construction, there was decided to standardize structures in typical building. The
purpose of this work was to make a standardized series of the roofing truss
designs with 10 % slope for 24, 30, 36 meters spans and different load
combinations.
Calculations were made in SCAD Office, in Microsoft Excel and some simple
calculations were made by hands. All calculations (determination of the load
bearing capacity and welded connections strength) were made according to the
Russian code SP16.13330.2011 «Steel Structures». On this calculations basis
BIM models in Tekla Structures were made. The metal consumption and all the
standard sections drawings were received from those BIM models.
Designed series of truss structures with a 10% slope and 24, 30, 36 meters
spans covers a range of line loads from 1.3 t/m to 3.3 t/m. In comparison with the
truss structures series Molodechno it has a lower metal consumption by reducing
the cross section of the upper chords due to vertical elements adding.
The result of this thesis work is a table for customers where they can choose
type of roofing structures they need and estimate the approximate weight and
cost, and almost the same table for designers – to consult customers and to
make some structure decisions according to customer needs. Therefore, this
series reduce the time spending from the moment of the concept project to the
moment of manufacturing because the time of designing is much less.
