I1 Construction task
Task
Students must in groups (1-3/group) check calculate a column (choose the column with the largest
normal force) and dimension a steel beam in a hall equipped with a traverse crane path. Granted
are attached figures and prerequisites as below.
Pillar
The columns are assumed to be hingedly attached to the beam and to the foundation. The columns are loaded eccentrically by
the traverse crane path and centrally of the roof beams. Load combination 6.10a and 6.10b (STR) shall
be used when dimensioning in failure limit states. No dimensioning in service limit
required. The column must be dimensioned in safety class 3. Effective cryptal for the column can
is set to 2. The columns are not assumed to be loaded by the wall's own weight, but wind load on the wall is assumed
load the column, you only need to consider wind load perpendicular to the long side of the building.
Steel beams
The steel beams to be dimensioned are those on which the traverse crane track runs (not themselves
the overhead crane beam, which the supplier is expected to dimension themselves). The beams must
performed with IPE cross section. The beams are assumed to be continuous along the entire length of the building
length (possible if joints are butt-welded). When calculating moment capacity, tilting shall
is taken into account through the factor χLT which is set to 0.66 for maximum support and field moments. The beams
dimensioned in failure limit with load combination 6.10a and 6.10b (STR) and in service limit
with load combination 6.15b, where maximum deflection is selected to span/500. The beams must
dimensioned in safety class 3.
Material
Concrete: C40
Reinforcement: K500B-T
Steel beams: S355
Loads
Loads are based on geographic location of building
Traverse crane track
The load consists of a permanent part (own weight) and a variable part. The variable load's
load reduction factors ψ0, ψ1 and ψ2 are set to 1.0. Since the load in a traverse is dynamic
origin, in a real case the load must be increased by a dynamic factor that depends on
the lifting class of the traverse. In this task, this factor is set to 1.0.
The size of the variable load is determined based on the last digit of the date of birth of the group
youngest member (if he was born in 970813, the number 3 applies).
Correspondingly, the terrain type around the building is determined based on the last digit i
the date of birth of the oldest member of the group.
