One of the most demanding jobs a structural designer is faced with, is the
dynamic analysis of an existing or proposed structure. To help solve these
difficult problems, Multiframe 4D brings dynamic analysis to the Multiframe
range. Using the same set of powerful and flexible modelling tools available in
all the Multiframe programs, 4D is the fastest way to determine the dynamic
response of the frames you are designing.
Multiframe 4D features a fast solver which uses sub-space iteration to quickly
find the natural modes, frequencies and periods of your structures. For more
complex problems, Multiframe 4D's time history response option allows you to
simulate the structure's response to seismic or other dynamic loading over time.
A built-in library of earthquake spectra can be used or your own dynamic data
sets can be entered and stored for future use.
Either lumped or distributed masses may be used to automatically take account
of the self weight of the structure. User control of the number of mode shapes
or time steps and convergence criteria make it easy for you to calculate a quick
estimate of dynamic response or a more rigorous and accurate solution. When
analysis is complete, a click on a joint or member reveals a graph of its
response over time. Alternatively, the whole structure can be animated to show
the total structural response.
