Seismic Code Parameters Wizard

Image Modified

It displays the analysis settings wizard where the parameters specific to IBC are determined step by step. On the wizard screen, you can assign the site class, risk category, horizontal and vertical response spectrum, seismic design category, stories, stories, structural system, diaphragm, structural system type ​​to be used.

Structural system type

Image Modified

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

Response modification coefficient

Image Modified

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

Overstrength factor

Image Modified

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

Deflection amplification factor

Image Modified

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

Redundancy factor

Image Modified

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

ELF Ct parameter

Image Modified

It is the ELF Ct parameter. This row is automatically refreshed when the structural system type is chosen.

ELF x parameter

Image Modified

It is the ELF x parameter. This row is automatically refreshed when the structural system type is chosen.

Accidental eccentricity ratio

Image Modified

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

Use custom vertical seismic load factor

Image Modified

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

Structural system

Image Modified

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.

Building Risk Category
