ACI 318-08 Design of Retaining Wall with Counterfort
Slab consists of two types which are one way slab and two way slabs.
One way slab has two types namely simply supported slab and one way continuous slab. While two way slabs also consist of two types namely simply supported two way slab and constrained slab. Slab types can be decided through side ratio calculation through BS8 110 reference such as:
- Ly / Lx <2.0 (two way)
- Ly / Lx > 2.0 (one-way)

This Proforma calculates bending moments and shear forces for loads on a single span or continuous multi-span beam using the moment distribution method. Static point or distributed loads may be analysed. Settlement at the supports may also be analyzed.
1.Enter data in the yellow cells only.
2.Enter the Span Length for each span. Any number of spans may be analyzed up to a maximum of 10. Any of the 10 spans not used will be removed when loads are added. (Note: The print-out for more than 8 spans requires the paper orientation to be set to 'Landscape').
3.Enter Modulus of Elasticity (E) multiplied by the Second Moment of Area (I) for each span. Relative values of EI may be used providing settlement effects are not required, for example, if the beam is of the same material and cross section throughout then a value of 1 may be entered for EI for each span. If settlement of the supports is being considered then actual stiffness values of EI (measured in kNm2) need to be entered.
4.Loads are entered by clicking the "Add Loading" button and selecting appropriate options from the screens that follow. Loads are entered span by span by clicking the "Add" button. When all the loads have been added then click the "OK" button to calculate bending moments and shears together with moment and shear diagrams.
5.The bending moment and shear can be calculated for any point on the beam by clicking the "Moment & Shear at a Point" button after the loading has been added.
Line Beam Analysis for Static Loads
FRAME is a spreadsheet program written in MS-Excel for the purpose of plane frame analysis of portal and gable rigid plane frames subjected to various types of loading. Specifically, the "stiffness matrix" method of analysis is used to determine the unknown joint displacements, support reactions, and member end forces. Individual frame members are also analyzed to determine the shears and intermediate moments. Plots of both the shear and moment diagrams are also produced. Also, the frame is drawn for visual confimation of geometry/configuration.
Program Assumptions and Limitations:
1. This program uses the "stiffness matrix" method of analysis and four (4) following basic analysis assumptions:
- Members must be of constant cross section (E and I are constant for entire length).
- Deflections must not significantly alter the geometry of the problem.
- Stress must remain within the "elastic" region.
- Since this analysis is "first-order", the effects of "P-D", "P-d", and shear deformation are not included.
2. Additional assumptions and features are as follows:
- Frame support joints may each be either fixed or pinned.
- Frame support joints may be at different levels (elevations).
- Columns must be vertical (cannot be sloped).
- For a portal frame, the top (roof) member may be flat or sloped in either direction.
3. A vertical load, horizontal load, and externally moment may be applied to any of the joints of the frame. These joint loads are to be applied in "global" axes directions. Note: Joint loads applied directly at supports are merely added directly to support reactions and are not reflected in member end force values.
4. On any individual member, this program will handle up to five (5) full uniform, partial uniform, triangular, or trapezoidal loads, up to ten (10) point loads, and up to four (4) externally applied moments. For vertical members, distributed loads and point loads are input in a "X-Global" sence of direction. For flat or sloped top (roof) members, distributed loads may be applied global over actual member length or applied global over the "projected" member length. Program designations are "Y-Global", "Y-Projected", "X-Global", and "X-Projected".For a flat top (roof) member of a portal frame, "Y-Global" and "Y-Projected" loads produce the same results.Uniformly distributed gravity (dead or live) load would be an example of a "Y-Global" distributed load on a sloped top (roof) member, while lateral uniformly distributed wind load on sloped top (roof) member would be an example of an "X-Projected" distributed load. A uniformly distributed load such as wind suction perpendicular (normal) to a sloped top (roof) member must be resolved into Y-Global and X-Global component values by user.
5. This program will calculate the member end reactions, the member end forces (axial, shear, and moment), the member maximum positive and negative moments (if applicable), and the joint displacements. The calculated values for the maximum moments are determined from dividing the member into fifty (50) equal segments with fifty-one (51) points, and including all of the point load and applied moment locations as well. (Note: the actual point of maximum moment occurs where the shear = 0, or passes through zero.)
6. The user is also given the ability to select an AISC W, S, C, MC, or HSS (rectangular tube) shape to aide in obtaining the required moment of inertia for input. (This facility is located off to the right of the main page.)
7. This program contains numerous “comment boxes” which contain a wide variety of information including explanations of input or output items, equations used, data tables, etc. (Note: presence of a “comment box” is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move the mouse pointer to the desired cell to view the contents of that particular "comment box".)
Portal and Gable Rigid Plane Frame Analysis
ASCE705W is a spreadsheet program written in MS-Excel for the purpose of wind loading analysis for buildings and structures per the ASCE 7-05 Code. Specifically, wind pressure coefficients and related and required parameters are selected or calculated in order to compute the net design wind pressures.
This program is a workbook consisting of nine (9) worksheets, described as follows:
- Simplified - Analysis using simplified method for low-rise buildings with h <= 60’
- MWFRS (Low-Rise) - Main Wind-Force Resisting System for low-rise buildings with h <= 60’
- MWFRS (Any Ht.) - Main Wind-Force Resisting System for buildings of any height
- Wall C&C - Analysis of wall Components and Cladding
- Roof C&C - Analysis of roof Components and Cladding
- Stacks & Tanks - Analysis of cantilevered chimneys, stacks, and vertical tanks
- Open Structures (no roof) - Analysis of open structures without roofs
- Wind Map - Basic wind speed map (Figure 6-1 of ASCE 7-05 Code)
Program Assumptions and Limitations:
1. Worksheet for "Simplified" analysis is applicable for low-rise buildings meeting the criteria of Section 6.4.1.
2. In the worksheet for Simplified analysis, the design MWFRS wind load is calculated for each direction. The design MWFRS load is assumed to be the total wind load on either the width or the length of the building respectively.
3. Worksheet for "MWFRS (Low-Rise)" is applicable for low-rise buildings as defined in Section 6.2.
4. Worksheets for "MWFRS (Any Ht.)", "Wall C&C", and "Roof C&C" are applicable for buildings with mean roof heights of up to 500 feet.
5. In worksheets for "MWFRS (Any Ht.)", "Wall C&C", and "Roof C&C" the user may opt to utilize user designated steps in height, 'z', in determining the wind pressure distribution.
6. Worksheets for "MWFRS (Any Ht.)", "Stacks & Tanks", and "Open Structures" can handle “rigid” as well as “flexible” buildings and structures. For “rigid” buildings or structures, this program uses the smaller value of either 0.85 or the calculated value from Section 6.5.8.1 of the Code for the gust effect factor, 'G'. For “flexible” buildings or structures, this program calculates the gust effect factor, ‘Gf’, per Section 6.5.8.2 of the Code based on the assumed formula for the fundamental period of vibration from Section 12.8.2.1 of the Code, where the exponent 'x' in the formula T = Ct*h^x is assumed to be 0.75.
7. Worksheets for "Wall C&C" and "Roof C&C" are applicable for flat roof buildings, gable roof buildings with roof angles <= 45 degrees, and monoslope roof buildings with roof angles <= 3 degrees.
8. Worksheet for "Stacks & Tanks" is applicable for cantilevered structures up to 600 feet tall.
9. Worksheet for "Open Structures" is applicable for open structures without roofs up to 500 feet tall. This can be utilized for open process-type structures as well as pipe/utility racks and bridges.
10. This program uses the equations listed in the reference, “Guide to the Use of the Wind Load Provisions of ASCE 7-02” for determining the external wind pressure coefficients, ‘GCp’, used in the Wall C&C and Roof C&C worksheets. (Note: a version of this document applicable to the ASCE 7-05 Code was not available.)
11. This program contains numerous “comment boxes” which contain a wide variety of information including explanations of input or output items, equations used, data tables, etc. (Note: presence of a “comment box” is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move the mouse pointer to the desired cell to view the contents of that particular "comment box".)
