c)  Using the Supplementary tables of AS1684, specify the

Lintels over all openings on the Ground Floor Plan and the First Floor Plan. Use F17 timber for all lintels.

d) Choose a single wall only that contains at least one window and sketch its elevation on the given blanks. You only need to sketch the timber framing. Revisit your sketch and adjust if necessary after completion of Parts 2 and 3.

Notes:

1. The specified F17 lintels will only support the timber framing. In external walls, to support the Hebel PowerPanel and Blockwork (as shown on Drawing A16) use additional galvanised steel lintels as following:

For openings 600 - 1200mm: 85 x 7 Flat Bar

For openings 900 - 2100mm: 100 x 100 x 10 Angle

For openings 2100 - 3000mm: 150 x 100 x 10 Angle.

Detail 02 or Drawing A17 shows a typical window head with a timber lintel and a galvanised steel lintel.

2.  The garage lintel has been already designed (B1).

3. You do not need to design the walls around the stairs.

2. Design of bracing:

Follow the relevant tutorial to design and specify the bracing on the Ground Floor Plan and the First Floor Plan. Use only 2 types of bracing: “d” and “h(B)”. Markup the blank for both plans and then, on a sperate blank, draw a typical elevation of “d” and h(B)” bracings.

Notes: You do not need to design the bracing for the decking posts. These have been designed and specified and will not contribute to the bracing of the rest of the house.

2.1 Design check of “d” bracing (ENG736 students only):

Choose a wall with braced using method “d”. Calculate the actual tension on the brace resulting from the nominal bracing capacity and compare it to the actual tensile capacity of the strap. Comment on the results in no more than 100 words.

Hint: use the published guides by the manufacturer to find out the actual capacity of the strap brace.

3. Design of the tie-downs and shear connections (if required):

Follow the relevant tutorial to design and specify the tie downs and shear connections (if required). You do not need to markup those on the plans, instead, you only need to complete a schedule for specific tie-downs and shear connections (if required). You will need to sketch an elevation/detail of each specific tie-down and shear connector you decide to use in your project.

3.1 Design capacity of tie-down (ENG736 students only):

Calculate the withdrawal capacity of the screw used in tying down the batten to the truss/rafter using AS 1720. Comment on the results in no more than 100 words (i.e. how do these results compare to those in AS 1684?)

Hints and Notes:

You can snap and paste the provided sketches and/or snap and paste sketches and diagrams from the lecture notes, AS1684 or other industry guides into your blanks (you will need to modify them to suit your project of course).

All drawings are drawn to scale (as indicated on each drawing). Refer to the attached rubric for more information about grading. You can printout the provided blanks and do your markups and sketches by hand and then scan them for your submission.

Alternatively, you can use a PDF editor to do the markups and sketches electronically. I personally use the free version of “PDF-
