2.1 TITLE OF LABORATORY EXPERIMENT
Portal Frame.
2.2 OBJECTIVES OF THE EXPERIMENT
1. To establish the relationship between applied load and horizontal displacement at the roller
support.
2. To observe the effect of the load position on the roller displacement.
2.3 EQUIPMENTS AND MATERIALS
The apparatus comprise of:
Support Frame
Photo
Vernier Caliper
Portal Frame Ruler/Tape Measure
Dial Gauge 1 set of load
Theory:
The equations for the horizontal displacement at the roller support of a portal frame with one
pinned support and one roller support are given below:
SCAN Brief
2.5 EXPERIMENT PROCEDURE
1. Remove the pinned attached to the load cell so that the roller is free to move.
2. Place a load hanger at the location where the load is to be applied, i.e. distance ‘a’ which is
equal to half of length L3.
3. Set the dial gauge reading to zero.
4. Place a load on the load hanger (10N).
5. Record the dial gauge reading. This represents the horizontal displacement at the roller
support.
6. Increase the load on the load hanger and record the dial gauge reading.
7. Repeat step 6 for another 4 equal load increments of 10N up to a maximum total load of
50N on the load hanger.
8. Tabulate your results.
9. Repeat the above procedure from step 1 to 8 for the value of ‘a’ equals 100mm and
300mm.

2.71 BACKGROUND INFORMATION
2.72 RESULTS AND CALCULATIONS
1. Draw the shape of the portal frame under test and give the important dimensions.
Indicate the position where the frame is loaded.
2. Calculate the stiffness (i.e. the load per unit deflection, W / δ) of the frame at the
point of loading.
3. Using the data in the Table above, draw the graph of load verses displacement at
the roller support. Draw the best fit curve through the plotted points.
4. From the graph determine the stiffness of the frame at the point of loading.
5. Plot the graph of load position against displacement.
2.73 DISCUSSION
1. Describe briefly the effect of load position on the roller displacement.
2. Comment on the accuracy of the experimental results.
3. List the probable factors that affect the accuracy of the results and steps to be
taken to overcome it.
2.74 ONCLUSION
1. From the result of this experiment, deduce the relationship between load and
displacement at the roller.
