Moment Frame Fabrication and Erection
A Moment Frame is a special type of steel frame that uses rigid connections between each of its constituent members.
This configuration is able to resist lateral and overturning forces because of the bending moment and shear strength that is inherent in its members and the connecting joints. Therefore, the stiffness and strength of the moment frame in seismic design depends on the stiffness and strength of its members.
Moment Frames are designed to carry vertical and horizontal loads in the same plane but may also be design on to provide resistance to horizontal loads out of the plane of the frame. Our steel moment frames are the base off our new buildings, and also to reinforce old constructions that need it according the California code.
The Mandatory Retrofit Program consists of multi-city ordinances passed in Los Angeles, San Francisco, Berkeley and Oakland to establish and enforce new building standards that reduce hazardous structural conditions. The purpose is life safety and injury reduction from buildings that are known to be vulnerable to earthquakes.
The Northridge earthquake in 1994 (Epicenter: San Fernando Valley) revealed a common flaw in steel-frame construction, poorly welded moment connections, and building codes were revised to strengthen them, by Mandatory Retrofit Program
