Appendix A: GUIDELINES FOR THE SEISMIC RETROFIT OF EXISTING BUILDINGS
CHAPTER A1
SEISMIC STRENGTHENING PROVISIONS FOR UNREINFORCED MASONRY BEARING WALL BUILDINGS
User note:
About this appendix: Appendix A provides guidelines for upgrading the seismic-resistance capacity of different types of existing buildings. It is organized into separate chapters that deal with buildings of different types, including unreinforced masonry buildings, reinforced concrete and reinforced masonry wall buildings, and light-frame wood buildings.
A403.10 Steel retrofit systems. Steel retrofit systems shall¶
have strength and stiffness sufficient to resist the seismic loads and shall conform to the requirements of this section.
A403.10.1 Special moment frames. Steel special moment frames shall comply with all applicable provisions of AISC 341, except that Section E3.4a addressing strongcolumn/weak-beams of AISC 341, is not required for columns that carry no gravity load.
A403.10.2 Inverted moment frame systems. Cantilevered column systems shall be permitted to be designed as inverted special, intermediate or ordinary moment frames, with corresponding moment frame seismic design coefficients, where the system satisfies the following conditions:
- The columns carry no gravity load.
- The columns are configured in pairs or larger groups connected by a continuous reinforced concrete foundation or grade beam.
- The foundation or grade beam shall be designed to resist the expected plastic moment at the base of each column, computed as RyFyZ in accordance with AISC 341.
- The flexibility of the foundation or grade beam, considering cracked section properties of the reinforced concrete, shall be included in computing the deformation of the steel frame system.
- The column height shall be taken as twice the actual height when checking lateral torsional buckling.
