scope:

This guide includes a discussion of the material characteristics of ASTM A1035/A1035M steel bars and recommends design criteria for beams, columns, slab systems, walls, and footings for Seismic Design Category (SDC) A, B, or C. For a lack of adequate data, the application of this guide for SDC D, E, or F is limited to slab systems, foundations, and structural components not designated as part of the seismicforce- resisting system but explicitly checked for the induced effects of the design displacements. The only exception is the use of transverse reinforcement for concrete confinement with a specified yield strength, f_y, up to 100,000 psi (690 MPa) for special moment frames, special structural walls, and coupling beams as permitted by Section 21.1.5.4 of ACI 318-08. Refer to Section 10.1 of this guide for more information on seismic design considerations. Shells and folded plate members and prestressed concrete are beyond the scope of this guide. Design examples are included to illustrate design procedures and proper application of the design criteria. Modifications to these design criteria may be justified where the design adequacy within the scope of this guide is demonstrated by successful use, analysis, or test.
