Schedule of Project Deliverables

Table of Contents

As noted earlier, the project is divided into 5through-the-semester activities with a culminating final activity that replaces your final course exam. A description of the four activities along with tentative due dates are provided as follows:

Activity	Description of Required Tasks*	Due Date
Gravity Roof Loads	Determine any missing building dimensions relative to wall heights. Estimate the basic roof dead load Determine member's t.a. For each typical member, calculate the roof live load and snow load in plf. Determine the total dead in plf for each member taking care to include self weights Tabulate your results: for each member, list L, t.w., t.a., D, S, Lr, w(D +self), wS, wLr	9/13
Wind	For both short and long directions: Calculate and sketch the overall building pressure diagrams for the LFRS. Check your building's enclosure status Determine the uniformaly distributed diaphragm load. Calculate the shear wall forces. Along the perforated walls, distribute forces to piers based upon pier length Extra credit will be given if distributed based upon the relative rigidity of the piers. Determine and sketch the wind forces acting normal to the walls.	9/25
Seismic	For both short and long directions: Calculate the base shear coefficient for the LFRS Determine the uniformaly distributed diaphragm load. Calculate the total shear wall forces. Along the perforated walls, distribute forces to piers based upon pier length Extra credit will be given if distributed based upon the relative rigidity of the piers. Determine the seismic forces acting normal to the walls. Select your wall to diaphragm anchorage for the critical load case (wind vs. seismic). For the critical lateral load case (wind vs seismic), check all necessary shear walls for overturning.	10/13
Wood Beams	For the sub-purlins, purlins, and girders; complete the following: Layout the 8' panel spacing for your "b". Identify the critical load combinations(s) for each roof member. Summarize the results of your load combination work (loads developed from your first, second and third project assignments) in your roof member table (this is the table you started in the first project assignment). Design the members; checking bending, shear, and deflection. (This work may require an adjustment to your w(D +self) from project 1 as you refine your member sizes.) Add your design results to your roof member table. Select hangers and girder seats from Simpson catalogue. Extra credit: Design your girder system as an cantilever beam system like that shown in Breyer starting on page 6.67.	11/3
Wood Diaphragms	Design the roof panel for both vertical and lateral loads. Carefully summarize panel thickness, grade, type, and nailing requirements. If possible, locate where the minimum nailing requirments can be started as a function of reduced unit shear. Design the bond beams	11/13

*Note: This list of required tasks per activity does not represent the full set of tasks per topic. If possible, you should try to go beyond this required list and complete as much as possible per activity to insure success with the project and to ease the end-of-the-semester burden with the final activity.

The final exam consists of the:

Correcting your project assignments. (Really, to make life much easier, you should be correcting each assignment after its been returned to you, prior to moving onto the next assignment.)
Addressing any missing design elements and finishing the building design.
Sketching all details and construction of a document/design key.
Completing any of the extra credit items, that are each worth a maximum of 50 points if completed correctly. These extra credit items are: a cantilever-drop beam system, the ledgers, pilasters, the pipe columns, or foundations.
Compiling your results into a neat and organized set of structural building calculations. A suggested table of contents for your design report is provided below.

This exam is due on or before 9:30 am on December 13, 2000. Your set of calculations must contain a table of contents, a framing key, a material and allowable stress summary, loading analyses, design calculations, and connection details that are referenced to both the calculations and framing key. The building elements you must consider included:

The roof structure that includes the structural-use panels, subpurlins, purlins, glulams, and all associated connection hardware with consideration of uplift.
All lintels and bond beams, including wall chord designs and seismic hardware.
If time permits, all load-bearing and non-load bearing exterior walls including parapets.

(requires page numbers and doesn't include extra credit)

Building Design Summary:

State your project givens.
State other design criteria including allowable stresses and deflection criteria and assumptions.
Roof and wall plans:
1. fully dimensioned.
2. for each element that was designed, identify on plan and key to the calculations
3. Typical cross-sectional details with all elements identified.
  1. in example: beam to beam, beam to ledger, etc.

Building Load Analysis:

Summarize roof member design loads.
1. For each member including the panels, state span; tributary width; D, L_r, S, W in psf and plf; load combination totals.
Supporting Calculations:
1. Vertical - provide the supporting calculations for:
  1. basic dead
  2. live
  3. snow
2. Lateral - provide all supporting calculations for:
  1. Wind - develop for both short and long directions when appropriate:
    1. Overall building pressure diagrams for LFRS - recheck your building opening status.
    2. Diaphragm loading.
    3. Shear wall forces.
    4. Wind forces normal to the walls.
  2. Seismic - develop for both short and long directions:
    1. Base shear coefficient for LFRS.
    2. Diaphragm loading.
    3. Shear wall forces at mid height.
    4. Seismic forces normal to the walls.
    5. Seismic anchorage force and anchor design.
  3. Critical loads per element - compare wind and seismic calculations and determine which load is critical for each design element including.
    1. Diaphragm loading in each direction.
    2. Shear wall forces.
    3. Forces normal to walls.
3. Overturning Analysis:
  1. For your critical walls (at least on in each building direction), check your overturning potential based upon the critical load. If you have a problem, determine how big your footer may have to be to counter-act the overturning potential.

Member Design:

Roof sheathing design and complete calculations for both vertical and lateral loads.
1. State thickness, grade, type, nail size, nailing requirements, blocking or edge support requirements.
2. If possible, locate where the minimum nailing requirements can start due to reduced shear as a function of diaphragm span.
Design wall bond beams - be consistent with wall rebar sizes.
Roof member design - for the critical load case(s):
1. Summarize your results in tabular form using previous roof plan identification. In this table, identify label, span, on-center spacing, critical loads, species, grade, size, corresponding typical details, and support hardware.
2. Design each member, checking bending, shear, deflection, and, if appropriate, check compression perpendicular to grain. Take care to use sizes that are readily available.
3. Select your hangers, beam seats, and/or column caps.
4. If using glued laminated beams, indicate desired camber.
Lintel designs:
1. Design a typical lintel that spans over the door openings. Consider bending and shear for the appropriate load combinations. Don't forget roof tributary loading and take the worse case loading. Check if arching action occurs.
2. Design the larger lintel that spans the window openings. Consider bending, shear, and deflection for the appropriate load combinations. Don't forget roof tributary loading and take the worse case loading. Check if arching action occurs.
