Elastic frame element - elfrm

There are cases where the use of an inelastic frame element is not required (e.g. members subjected to low levels of excitation and thus responding within their elastic range). For such cases, the employment of an elastic linear frame element might be desirable, for which reason element type elfrm has been developed and implemented in SeismoStruct.

Note: In the elfrm element, P-delta effects as well as large displacement/rotation effects are dully taken into account.
