Structural system type

Open

The type of structural system for X and Y direction is selected in accordance with the design of the building.

Response modification coefficient

It is the response modification coefficient value. This row is automatically refreshed when the structural system type is chosen.

Overstrength factor

It is the strength excess coefficient value. This row is automatically refreshed when the structural system type is chosen.

Deflection amplification factor

It is the deflection amplification factor value. This row is automatically refreshed when the structural system type is chosen.

Redundancy factor

It is the redundancy factor value. This row is automatically refreshed when the structural system type is chosen.

Accidental eccentricity ratio

The eccentricity ratio to be used during the analysis is given as a percentage.

Use custom vertical seismic load factor

If checked, the custom vertical seismic load factor which entered in "factor to use (instead of 0.2 SDS)" line is used.

Structural system

If the building block consists of only concrete elements, Concrete; if it consists of only steel elements, Steel; Steel + Concrete option is selected if it consists of concrete and steel elements.
