Analisis Respon Spektral

Specifying Structure Mass

Defining Eigenvalue Analysis Control

Response Spectrum Functions

Response Spectrum Load Cases

Response Spectrum Results

Workshop

midas Civil



The structure Mass can be defined in one of the following ways:

Lumped Mass Consistent Mass

Lumped Mass

The total mass of an element is directly distributed to the nodal points of an element.

Consistent Mass Consistent Mass is calculated with the shape function used to derive the stiffness matrix

Workshop

Step 1: Define Structure Mass

midas Civil



Lumped mass can be defined in:

1. Structure Structure Type.

2. Load Static Loads Load to Masses

Workshop

midas Civil



Consider off Diagonal mass

Consider the mass at the centroid of the section

If the offset is defined.

Workshop

midas Civil



Convert Self-weight into Masses

The masses of the elements included in the model can be automatically converted into lumped masses or consistence masses in midas Civil for dynamic analysis or computation of statically equivalent seismic loads. When dynamic analysis is performed with "Do not convert" option checked, mass effect cannot be reflected in the analysis.

midas Civil



Analysis -> Eigen Value Analysis Control

Subspace Iteration

This method is effectively used when performing

eigenvalue analysis for a finite element system

of a large scale (large matrix system)

Lanczos

Tri-diagonal Matrix is used to perform eigenvalue analysis.

This method is effectively used when

performing eigenvalue analysis for lower modes.

If the model is complex this analysis is fast.
