"WELDGRP" Program

Doc"WELDGRP" --- WELD GROUP ANALYSIS PROGRAMProgram Description:"WELDGRP" is a spreadsheet program written in MS-Excel for the purpose of analysis of weld groups usingeither the ultimate strength method (also known as "instantaneous center of rotation" method) or the "elastic"(vector) method ("Alternate Method 1" in AISC Manual). A separate worksheet contains data tables for welds.This program is a workbook consisting of eleven (11) worksheets, described as follows:Worksheet NameDescriptionDocThis documentation sheetTable XIXWeld group instantaneous center analysis for vertical parallel weldsTable XXWeld group instantaneous center analysis for horizontal parallel weldsTable XXIWeld group instantaneous center analysis for vertical rectangular weldsTable XXIIWeld group instantaneous center analysis for horizontal rectangular weldsTable XXIIIWeld group instantaneous center analysis for C-shaped welds (case 1)Table XXIVWeld group instantaneous center analysis for C-shaped welds (case 2)Table XXVWeld group instantaneous center analysis for L-shaped welds (case1)Table XXVIWeld group instantaneous center analysis for L-shaped welds (case 2)Weld Group (elastic)Weld group elastic analysis for up to 24 total weld lines and 4 load pointsWeld DataFillet Weld Data TablesProgram Assumptions and Limitations:1. The AISC eccentric loads on weld groups worksheets (Tables XX through XXVI, pages 4-75 through 4-82) areapplicable for only in-plane shear loads and torques (moments) on the weld group. With the one exceptionbeing the "Special Case" of out-of-plane loading for vertical parallel welds, AISC Table XIX.2. The "Weld Group (elastic)" worksheet can be used for all cases of in-plane and out-of-plane loads on the weldgroup, or where geometry limitations of the AISC Tables XIX through XXVI are ecceeded. The "elastic" method(AISC "Alternate" Method 1) will always give conservative results when compared to using the AISC Tables.3. The "Weld Group (elastic)" worksheet assumes a minimum of 1 weld and a maximum of 24 welds in a group.4. In the "Weld Group (elastic)" worksheet, the welds are treated as "lines" possessing a length, but no actualtheoretical thickness. All welds are assumed to contribute to the moment of inertia of the group, and theapplied loads are linearly distributed among the welds based on the location of the welds from the centroidalaxes.5. In the "Weld Group (elastic)" worksheet, the weld group must be composed of straight lines/segments, butthey all need not be connected. Circular or portions of a circular pattern weld may be adequately modeled byusing a series of segments.(Note: see below for an example of modeling a circular weld pattern.)6. In the "Weld Group (elastic)" worksheet, each weld line/segment is defined by its own start (X1,Y1) and end(X2,Y2) sets of coordinates. Coordinates defining weld lines/segments can be input irrespective of direction.That is, a weld line/segment may be defined from left-to-right and top-to-bottom or vice-versa.7. The "Weld Group (elastic)" worksheet assumes an orthogonal X-Y-Z coordinate system. All welds and loadspoints MUST BE located in the "positive" (1st) quadrant. "Negative" weld or load point locationcoordinates are NOT permitted. "Right-Hand-Rule" sign convention is used for all applied forces and momentsat load point locations.8. In the "Weld Group (elastic)" worksheet, the welds and load points can be numbered in any desired order.However, the user should make sure to either clear the contents of all spreadsheet cells that are not used forinput or those cell values should be input = 0. All welds and load points MUST BE input in proper numericalsequence with no "breaks" in the numerical order of input data.9. The "Weld Group (elastic)" worksheet calculates the required weld size in terms of both fillet leg and effectivethroat dimensions, based on the assumption of using E70XX welding electrodes. The user should check AISCspecification for limitations on minimum and maximum weld sizes.10. This program contains numerous comment boxes which contain a wide variety of information includingexplanations of input or output items, equations used, data tables, etc. (Note: presence of a comment boxis denoted by a red triangle in the upper right-hand corner of a cell. Merely move the mouse pointer to thedesired cell to view the contents of that particular "comment box".)11. Weld Data worksheet shows data tables for minimum size of fillet welds, allowable force on fillet welds, andintermittent fillet weld lengths and spacings.Circular Weld Example (using elastic method):A circular weld of diameter, 'D', with its center located at 0.50*D from both the origin X and Y axes, may bemodeled as 24-sided shape inscribed within the circle. The coordinates of the 24 connected segments canbe described as follows:Weld Coordinates:StartEndX1Y1X2Y2Weld #100.50*D0.0170*D0.3706*DWeld #20.0170*D0.3706*D0.0670*D0.2500*DWeld #30.0670*D0.2500*D0.1464*D0.1464*DWeld #40.1464*D0.1464*D0.2500*D0.0670*DWeld #50.2500*D0.0670*D0.3706*D0.0170*DWeld #60.3706*D0.0170*D0.50*D0Weld #70.50*D00.6294*D0.0170*DWeld #80.6294*D0.0170*D0.7500*D0.0670*DWeld #90.7500*D0.0670*D0.8536*D0.1464*DWeld #100.8536*D0.1464*D0.9330*D0.2500*DWeld #110.9330*D0.2500*D0.9830*D0.3706*DWeld #120.9830*D0.3706*D1.0*D0.50*DWeld #131.0*D0.50*D0.9830*D0.6294*DWeld #140.9830*D0.6294*D0.9330*D0.7500*DWeld #150.9330*D0.7500*D0.8536*D0.8536*DWeld #160.8536*D0.8536*D0.7500*D0.9330*DWeld #170.7500*D0.9330*D0.6294*D0.9830*DWeld #180.6294*D0.9830*D0.50*D1.0*DWeld #190.50*D1.0*D0.3706*D0.9830*DWeld #200.3706*D0.9830*D0.2500*D0.9330*DWeld #210.2500*D0.9330*D0.1464*D0.8536*DWeld #220.1464*D0.8536*D0.0670*D0.7500*DWeld #230.0670*D0.7500*D0.0170*D0.6294*DWeld #240.0170*D0.6294*D00.50*D

all cells that are not used for input of weld coordinates, or those cell values should be input = 0.The 'Y1' coordinate is the y-distance from the origin axis to the start of a particular weld line/segment.The 'X2' coordinate is the x-distance from the origin axis to the end of a particular weld line/segment.The 'Y2' coordinate is the y-distance from the origin axis to the end of a particular weld line/segment.The total length of all weld lines/segments, 'Lw', is calculated as follows: Lw = S (L)where: L = length of each weld line/segment = ((X2-X1)^2 + (Y2-Y1)^2)^(1/2) X1,Y1 =
