You are part of the construction team on site. Your area of responsibility is the preparation / sketching of structural details for the onsite contractors. Sketching Criteria:

Before attempting this assignment re read the Introduction module on sketching in the study materials. You are a Site Engineer and creating these details for construction or fabrication. RFI’s (requests for information), questions or clarification, will slow the project down and you are already behind the program. So details need to be clear and easy to understand and: •

Labelled, neat and uncluttered. Use a scale ruler and sharp dark pencil for hand sketching. Marks deducted for poor sketching.

•

complete – that is, they should show all elements and relationship of construction in the detail, e.g., scale used, member sizes, spacing, concrete cover, weld details, bolt sizes, dimensions, centre lines, section notes etc.

•

prepare the sketches on A4 plain paper for the contractor to be able to build

Note: There is no one correct answer to the sketching questions as students may produce a sketch using different forms of connection, the sketch will dictate the detail required, e.g., bolted as against welded connections. As this is a detailing exercise, you can ignore specific design requirements. You are required to fully label and sketch the following structural details. All dimensions given are in mm: (A typical set of Assignment 2 sample answers will be available on Study Desk after we release the marked assignments). Assignment submission: 1) Scan all the hand sketches together to a single pdf 2) Submit Revit (or a similar software) drawing in pdf format using the assignment 2 submission box in the study desk.

2

Refer to Drawing Sheet No. 11.1 on p2 Footing Plan, for questions 1 and 2:

1.

Hand sketch an elevation and plan view detail of a pad footing and column on Grid 2A at scale 1:10 (40 Marks)       

2.

Pad size is 800 x 800 x 400 Deep Pad reinforcing 8 N16 both ways Column Size 400 x 400 square Column reinforcing is 4 N24 with R8 ties @ 250 crs Assume 2 pours, 1 for pad footing, 1 for column Assume 50 cover below ground, 40 cover above ground Ground level finishes at the top of the footing

Hand sketch a Cross Section of Strip Footing SF2 across the footing showing the 2 block walls at scale 1:10 (40 Marks)

Strip footing - reinforcing 4 N16 Bottom and 5 N12 Top with ties R8@300, Assume 50 cover Corefilled Blockwork – 2 x 190mm block walls, 1.0m high with 40 cavity, each N12 @ 600 crs.

3.

Hand sketch the beam elevation below, showing approximately where the unbonded post tensioned tendons would be located: (10 Marks)

4.

For the simple column and beam structure shown here, hand sketch the theoretical deflected shape from a point load acting mid span on the beam. Assume both columns are restrained at the bottom. Do for beam to column joints (connections) that are: a) Fixed or Rigid b) Pinned or flexible

(20 Marks)

Beam

2 Columns

5.

Using Revit or a similar software, draw the required reinforcing steel for a typical reinforced concrete beam to column connection. (50 Marks) 

 

Do typical labelling excluding all reinforcing sizes and dimensions. Assume the reinforcing sizes and dimensions are being provided by others (the Structural Engineers) in the column and beam schedules. Draw an elevation of the connection and a section of the column For scaling purposes use 1:10 and assume beam is 400 x 600 Deep. Column is 400 square.

6. Draw an example of a structural steel shear connection of a secondary beam connecting at right angles with a primary beam. Ensure beams are drawn and labelled the correct size and at a scale of 1:10. Hint 1: 310 UB 32 is not 310mm high Hint 2: This is partly an exercise in looking up Australian structural beam sizes to find the dimensions. Connection details to be included are: 1. Primary Beam 310 UB 32 2. Secondary Beam 250 UB 25.7 3. Shop welded Cleat – 10mm plate, 3 holes to take 3 x M20 x 8.8/S Bolts Notes; the size of the cleat is to suit the connection. Show cleat and secondary beam web with a minimum 40mm edge distance for the bolt holes and indicate any welding required. Show 2 views of your beam to beam connection for clarity.
