Fig. 29. Layout and zones of influence <strong>for</strong> longitudinal and four-way riser sway bracing <strong>for</strong> System #3.<br />
Step 2. Calculate design loads. Using a 0.5 G factor and Schedule 40 pipe, horizontal seismic design loads<br />
on each brace will be as shown in Table 19.<br />
Step 3. Select the proper brace type, size, and maximum length. <strong>Based</strong> on the configuration of the brace<br />
connection to the structure, the angle of the brace from the vertical, and the calculated horizontal design load,<br />
the brace type, size, and maximum length can be selected from Tables 2 to 7.<br />
Step 4. Using the Step 2 design loads and the brace angle from the vertical, select the appropriate type<br />
and size of fastener <strong>for</strong> attachment to the building structure.<br />
