Call
From the Main Menu select [Results] tab > [Type : Analysis Result] > [Table] group > [Result Tables] > [Nodal Result of RS Table]
Input
(Refer to "Nodal Result of RS")
Select a vibration mode for which the natural vibration vector is to be generated, in the Records Activation Dialog.
In order to display the inertia forces and accelerations due to modal combinations, select only the Load Cases. In order to display inertia forces and accelerations for each mode, select the Load Cases as well as the relevant Modes
Refer to Usage of Table Tool and check the following data:
Results due to modal combination
Load Case : Response Spectrum Load Case
Modal Com. : Modal combination method
Node : Node of a structure
FX, FY, FZ : Nodal inertia force in each direction
MX, MY, MZ : Nodal bending moment in each direction
Mb : Warping moment
DX, DY, DZ : Nodal acceleration in each direction
RX, RY, RZ : Nodal rotational acceleration in each direction
RW : Warping acceleration
Results due to mode selection
Load Case : Response Spectrum Load Case
Mode : Mode selected in the Records Activation Dialog
Node : Node of a structure
FX, FY, FZ : Nodal inertia force in each direction
MX, MY, MZ : Nodal bending moment in each direction
Mb : Warping moment
DX, DY, DZ : Nodal acceleration in each direction
RX, RY, RZ : Nodal rotational acceleration in each direction
RW : Warping acceleration
Note 1
Inertial forces resulting from response spectrum analysis can be converted to nodal loads in the specified load case. The procedure is as follows:
Note 2
When Lumped Mass is selected in Structure Type, inertial force is calculated by Nodal Mass * Base Acceleration.
When Consistent Mass is selected in Structure Type and floor diaphragm is considered, inertial forces of slave nodes will be transferred into that of master node. Therefore inertial forces of slave nodes will be displayed as zero in the table. If there is no generated node in the master node position, inertial forces of all nodes will be displayed as zero.
When Consistent Mass is selected in Structure Type and floor diaphragm is not considered, inertial forces will be calculated using diagonal components in mass matrix.
