ENG 566 Project Different types of RC beams under bending
1. Aim and Background
The aim of the project is to (i) estimate the capacity of three different reinforced concrete beams using the theoretical formulations; (ii) comparing the accuracy of your estimates with the failure loads measured on the beams tested in the laboratory.
A total of three reinforced concrete beams, each having different reinforcement layouts, were tested to failure. The 3 beam types are:
Beam B1 Under-reinforced
Beam B2 Over-reinforced
Beam B3 No Stirrups
2. Test set-up
The test set-up, beam dimensions, reinforcement provided, material properties are as follows:
The three beams are designated B1, B2 and B3. All beams have the dimensions of 100 200 1500 mm. The two-point load arrangement and simple supports, and failure load Pu, are shown below. The characteristic compressive strength is 38 MPa. N20 and N12 have the yield strength of 520 MPa and R6 has a yield strength of 300 MPa.The cross section and reinforcement used in beams B1, B2 and B3 are shown below. Assume that Beams 1 and 2 are sufficiently reinforced in shear whereas Beam 3 has no shear reinforcement.
3. Submission for Assessment
Task 1: Each group of four students must calculate the predicted (theoretical) failure load Pu and present the detailed calculations. You must provide all necessary information (e.g. assumptions and/or justification of calculations aligning with standards and/or lecture notes) that support your calculated failure loads.
Task 2: After understanding the online materials (to be available), each group must submit a group lab
report by 5:00 PM on 01/10/2023 that compares the failure loads measured experimentally with those calculated on the basis of flexural or shear strength and discusses the observed types of failure and reasons why the failure loads are different to the calculated values.
Note: Lab report will have 10% of your final mark.
All necessary loading curves and pictures of the Tests have been uploaded on Learnline.
Note: The discussion you need to provide should be specific to this particular testing conducted. So providing general information/discussion using AI-generated text (e.g. ChatGPT) will not receive any mark.
Good Luck!
