•Each analysis reflects the state
of building at
the end of
previous analysis.
•All component actions are actually
action increments
•They have to be added up to
reflect
the analysis results.
•Generally, a substantial amount
of manual bookkeeping is involved.
•Results obtained by successive
linear analyses are inherently approximate,
incapable of accurate modeling of the P-D effects and weak in assessment of true member forces.
•Despite these facts, if used properly, it can provide a good approximation to the global force-displacement curve for
the building.
