AD_TRUSS and AE_BENT
Estimate structure, often the largest single cost.
| These programs are used for estimating weights of trusses and bents with sufficient accuracy for determining prices. | |
AD_TRUSS and AE_BENT APPLICATION |
|
| In many projects the cost of structural steel outweighs the cost of belt
conveyor components. For those making proposals or feasibility studies
these Programs help overcome delays frequent in obtaining a steel price
from outside sources.
AD_TRUSS BRIEFLY Program accessed from the desktop. User enters general parameters of truss on FrmTruss.
After clicking APPLY user will click 2 - SELECT MEMBERS. FrmHowe or FrmWarren will appear, example below.
By clicking specific MEMBER DESIGNATION in diagram and MEMBER SHAPE CHOICE in list then clicking 3 - SIZE MEMBERS user can then enter shape dimensions such as in FrmDimensionsAngle near bottom. After clicking APPLY and COMPUTE on FrmHowe the display will reflect that shown below.
INTERACTION results (yellow highlight) in excess of 1 indicate the member selected has insufficient strength. Through an iterative selection of stronger shapes the user will reduce the INTERACTION result, for each member, to less than 1. Where the INTERACTION result is dramatically less than 1 the user might consider members of less strength. In each case the user must consider how the FORCE in the member is resisted by end welded or bolt connections. ( 3/16 inch fillet weld typically resists 2,000 pounds per lineal inch. Example: A 12,000 pound force would require a minimum of 6 inches of weld at the joints. Size and shape of joined members must contemplate this.) From the STEEL WEIGHT SIMPLE SPAN at line 6 and scrolling down for STEEL WEIGHT CANTILEVER SPAN prices can be computed from fabricators cost per unit weight. This method draws on CHAPTER H, COMBINED STRESSES, Manual of Steel Construction, Allowable Stress Design, Ninth Edition, Page 5-54 including ALLOWABLE LOADS ON COLUMNS SINGLE ANGLE STRUTS, Page 3-55. Also See 3rd Edition LRFD, page 16.3-1. Scrolling further down, for technical interest, are computed shape properties. Developing shape properties from dimensions meets needs of international users. AE_BENT BRIEFLY Program accessed from desktop. User enters general parameters of bent on FrmBent.
After clicking APPLY user clicks SELECT MEMBERS. FrmBentDisplay appears.
By clicking specific MEMBER DESIGNATION in the diagram and clicking MEMBER SHAPE CHOICE in list then clicking 3 - SIZE MEMBERS enables shape dimension to be entered in form similar to FrmDimensionsChannel seen near bottom of display. After completing all members click APPLY and COMPUTE on FrmBentDisplay and results will appear on the same form similar to below.
Similar to AD_TRUSS, INTERACTION results (back color yellow) in excess of 1 are too weak. Through an iterative selection of stronger shapes the user must reduce the INTERACTION result, for each member, to less than 1. Where the INTERACTION result is dramatically less than 1 the user might consider lighter weight members. In each case the user must be aware of the FORCE in the member and visualize how those FORCEs are to be resisted by end welded or bolt connections. From the STEEL WEIGHT at line 6 price can be computed using fabricators unit cost basis. These programs are for expediting proposal preparation. |
