Question 1: Designing a Structural Beam
Your task is to design a reinforced concrete beam with the following specifications:
- Span: 6 meters
- Load: Uniformly distributed load of 20 kN/m
- Material: Grade 40 concrete with a yield strength of 28 MPa
- Required safety factor: 1.5
Solution:
Step 1: Determine the Design Load: Design Load = Uniform Load × Span = 20 kN/m × 6 m = 120 kN
Step 2: Calculate the Bending Moment: Bending Moment = (Design Load × Span^2) / 8 = (120 kN × (6 m)^2) / 8 = 540 kNm
Step 3: Select Beam Dimensions: Using the formula for bending moment in a rectangular beam: Bending Moment = (f * b * d^2) / 6 Where: f = Allowable stress b = Width of the beam d = Depth of the beam
Rearranging the formula to solve for d: d = ∛((Bending Moment * 6) / (f * b))
Given: f = 28 MPa Safety Factor = 1.5
Substitute the values and solve for d: d = ∛((540 kNm * 6) / (1.5 * 28 MPa * b))
Step 4: Reinforcement Design: Calculate the required steel reinforcement using design codes and standards such as ACI (American Concrete Institute) or Eurocode.
Question 2: Creating a Topographic Map
You are tasked with creating a topographic map of a site with the following contour lines:
- Contour Interval: 1 meter
- Known Spot Elevations: A (100 m), B (95 m), C (105 m)
- Additional Spot Elevations: D (98 m), E (102 m)
Solution:
Step 1: Plot Known Spot Elevations: Using AutoCAD, plot the known spot elevations A, B, and C on the drawing.
Step 2: Draw Contour Lines: Draw contour lines connecting points of equal elevation based on the contour interval and known spot elevations.
Step 3: Add Additional Spot Elevations: Plot the additional spot elevations D and E on the drawing.
Step 4: Label Contour Lines: Label each contour line with its corresponding elevation.
Step 5: Finalize the Topographic Map: Add necessary annotations, scale, legend, and title to complete the topographic map.
Conclusion:
Mastering AutoCAD is essential for civil engineering students to excel in their academic endeavors and future careers.
