700 GHS Structural Analysis

Homework 711 covers basic longitudinal strength.  The main focus of this homework is to understand the correct way to add weight items as distributed loads.  The light ship weight gets added as a distributed weight.  And there is a deadweight item also added as deadweight.  Tank weights are also included.  Finally, the homework covers how to define frame locations for a longitudinal strength analysis.  Download includes homework files and solution.

Edit 1:  The light ship weight distribution needed to modified, otherwise GHS was not happy.  Please use the following light ship weight distribution.

Location, Weight rate
0.0 m, 5.0 MT/m
10.0 m, 40.0 MT/m
90.0 m, 50.0 MT/m
100.0 m, 10.0 MT/m

TCG = 0.0 m
VCG = 3.0 m

The main challenge of this homework is how to properly define section properties in GHS.  Download includes homework files and solution.

Edit 1:  The section properties defined in the view are actually too small.  This is particularly a problem when you try to define the moment of inertia with extreme fiber distance.  The download includes some corrected values for section properties, already converted into the proper units.

This homework covers how to define waves in GHS.  Homework files and solution are included in the download.

Edit 1:  The wave amplitudes were specifically chosen to be obviously visible in condition graphics.  But they were actually too visible.  Please use the following wave configurations instead.

Sinusoidal Wave
180 deg phase
100 m length
3.0 m amplitude (6.0 m wave height)

Stokes Wave (In Place of Trochoidal Wave)
0 deg phase
30 m length
1.5 m amplitude (3.0 m wave height)
