What is Soil Structure Interaction?
The effects of soil-foundation interaction, e.g., the differential settlement, may have a significant impact on building response.
ETABS offers a modelling option to automatically generate foundation springs
and dashpots for isolated column footings (i.e., shallow foundations) based on
footing geometry and soil profile definitions. Soil profiles may consist of any
number of layers and associated properties, and there is no limit to the number
of footing and soil profile combinations that may be defined.
What are shoring piles?
Shoring is used to support a structure to prevent a collapse. The most common shoring techniques that we encountered are during the early stage of construction which is an excavation. Shoring is intended to support a deep excavation to prevent the ...
What is the Construction Sequence analysis?
Implicit in most analysis programs is the assumption that the structure is not subjected to any load until it is completely built. This is probably a reasonable assumption for live, wind and seismic loads and other superimposed loads. However, in ...
What is the difference between Time History and Response Spectrum?
Time History This method calculates the response of a structure subjected to earthquake excitation at every instant of time (hence the name Time History). Various seismic data are necessary to carry out the seismic analysis i.e. acceleration, ...
What is Power spectral Density analysis and Steady state analysis?
Power-spectral-density (PSD) analysis is a type of frequency-domain analysis in which a structure is subjected to a probabilistic spectrum of harmonic loading to obtain probabilistic distributions for dynamic response measures. A root-mean-square ...
What is partial release of fixity of beams?
The release is removing the capacity of a certain structural member to support forces like bending moment, torsion (more of torsion in the next posts) axial and shear forces. But most often release means release of the bending moment. Another ...
