General

Graphical representation of all the checks inthe STATIK-5 environmentOptional calculation of the first adequate sec-tion

Seismic Displacements and StoreysRotation Verification

Vibration periods based on dynamic analy-sis or according to simlified formulaeOptional direct input of seismic factorsDirect control of elastic response spectrumfor any combination of parametersInput of the contour of each floor for the veri-fication of the angular deformation of themasonry infills and the accidental mass ec-centricityAutomatic calculation of the torsional sensi-tivity of the storeyFactor è for p-Ä effectsEAK, EC8,SIA or arbitrary spectrum

Equivalent Seismic Static Loading andMasses

Definition of the level of the seismic baseReduction of variable (live) loads accordingto the codeUnitary triangular loading with an optionalconcentrated load on the top, as well as uni-tary loading of accidental eccentricity to avoidthe repetition of the analysis in case of chang-ing the seismic parametersDynamic multi-modal analysis with 6 de-grees of freedom per joint and optional ef-fective mass in x, y or z directionSecond order solution (when required)

Method of Dynamic Modal Analysis

Definition of seismic excitation directionsCombination of modes for each direction ofseismic excitation, based on code’s or arbi-trary spectrum, with calculation of the ratioof the participating massSuperposition for each direction and for allprobable seismic directions with various sta-tistical algorithms (SRSS, CQC, summationof absolute values)Calculation of the probable maxima of theinternal moments and forces, deformationsand support reactions)Option to apply different damping ratio foreach mode
