| == 18.5.1 Scope | |
| === 18.5.1.1 This section shall apply to intermediate precast structural | |
| walls forming part of the seismic-force-resisting system. | |
| == 18.5.2 General | |
| === 18.5.2.1 In connections between wall panels, or between | |
| wall panels and the foundation, yielding shall be restricted to | |
| steel elements or reinforcement. | |
| === 18.5.2.2 For elements of the connection that are not | |
| designed to yield, the required strength shall be based on | |
| 1.5Sy of the yielding portion of the connection. | |
| === 18.5.2.3 In structures assigned to SDC D, E, or F, wall | |
| piers shall be designed in accordance with 18.10.8 or 18.14. | |
| = R18.5 — Intermediate precast structural walls | |
| Connections between precast wall panels or between | |
| wall panels and the foundation are required to resist forces | |
| induced by earthquake motions and to provide for yielding | |
| in the vicinity of connections. If mechanical splices are used | |
| to directly connect primary reinforcement, the probable | |
| strength of the splice should be at least 1.5 times the specified | |
| yield strength of the reinforcement. | |
