3. Scan down the appropriate Design Load column until you find a cell (within your on-center spacing) that meets or exceeds the span of your application. 4. Select the TimberStrand® LSL joist depth. General Notes Table is based on: – Deflection criteria of L/360 live load and L/240 total load. – Uniform loads. – 100% load duration.

For simple span (5' minimum), uniformly loaded joists used in residential applications, one maximum size round hole may be located

Tables 4 and 10 provide similar infor-mation for floor members. The tables can be used to size such members for preliminary design. Final design should include a complete analysis, including bearing stresses and lateral stability. See Design Examples 2 and 3 (pages 24-25) for examples of preliminary design using glulam beam load-span tables.
How To Use The Column Load Tables Example 1 Design the lightest 6-inch square ERW HSS column of F y = 46 ksi (ASTM A500 Gr. B) to support a factored concentric load of 148 kips. The largest effective length, KL, is 16 feet. Enter the Fy = 46 ksi table (page 9) for the 6-inch square ERW HSS. Read across the row at KL = 16 ft. and note the following:
your design professional. 8. Capacity values have been calculated in accordance with the AISI 2001 design manual. 9. Values shown in the load tables for three or more spans are based on uniform bay spacings. If non-uniform bay spacings exist, contact factory.

This course provides a procedure for preparing a manual calculation for cooling load. A number of published methods, tables and charts from industry handbooks, manufacturer’s engineering data and manufacturer’s catalog data usually provide a good source of design information and criteria in the preparation of the HVAC load calculation.
ampacity of wire for any load. NEC 220-2, use NEC 310-16 for ampacity. This applies to not more than 3 phase conductors in 1 conduit. Warning Voltage Drop NEC 310-16 wire ampacity tables do not take into account voltage drop, only thermal limit. Overhead triplex, use 310-16 for wire ampacity. Rule of Thumb
These tables may be used for reference and design should be based on the methods that appear in this update. Indirect design method, using D-Loads, is a widely used empirical method for selecting and specifying pipes. The specified D-Load for a pipe is the minimum test load where cracks no more than 0.01 inch in width are generated in a three-
The design of the wooden deck follows the procedures of the Timber Bridges; Design, Construction, Inspection, and Maintenance, U.S. Forest Service, June 1990. Load factors of 1.2 and 1.6 were used for dead load and live load factoring, respectively. The bridge deck is not designed to carry the vehicular loads. The beam carries the load of the ...
