Objective
The main objective of the structures laboratory is to demonstrate and investigate experimentally the behavior of structural elements. To properly illustrate the structural behavior, tests of structural members to destruction are conducted. Tests have been carried out for the determination of the plastic bending capacity of steel beams and the ultimate strength of steel tensile member and steel beam column connections in supporting courses. The laboratory is also equipped with facilities to conduct experimental research in the area of the structural engineering.
Facilities
Size and capacity of work area
There are two work areas in the structures laboratory: (1) the Main Testing Area and (2) the Secondary Testing Area. The area of the main testing area is about 197 m2 (2140 ft2). It is a 2 cells RC box structure with 1000mm thick strong floor and tie down points on 600 mm x 600 mm grid. The design point load of each tie down points is 500 kN. A reaction strong wall of area about 48 m2 (2700 ft2) is located in the main testing area. It is a RC box structure with thickness of 1860mm and tie down points on 600 mm x 600 mm grid. The design point load of each tie down points is 250 kN. A three-dimensional 12.5-tone crane is installed in the main testing area. The area of the secondary testing area is about 155 m2 (1700 ft2) and several test machines such as the UTM and concrete compression test machines were located in this area.
Loading Frame
In the main testing area, there is two larger loading frames for structural members testing. With proper arrangement of the frame, the capacity of the frame can be achieved up to 1000 kN. Measurement of load, deflection and strain can be done by using a data acquisition system – Measurement Group System 5000. The system is connected through a personal computer that store and display the test data during testing. |
Instrumentation and Heavy Equipment
Compression Machine (5000 kN) |
![]() |
The compression machine is used for high capacity compression testing of concrete cylinders, cubes and block. For 5000kN capacity, it can cover most of general concrete testing.
Testing Applications

Actuator with 250kN capacity and 500 mm stroke
The actuator system is a component of the testing setup that is responsible for controlling the loading and displacement on the specimen testing
Testing Applications
- Metals—Bar, Plate, Pipe & Tube, Rebar, Structural
- Wire—Rod, Strand
- Concrete / brick—Beam, wall
Beams The laboratory also carries instrumentation such LVDT’s (25 mm to 250 mm run), load cells (one 50,000 lbs (222.4 kN) tension load cell, one 50,000 lbs (222.4 kN) compression load cell, three 30,000 lbs (133.4 kN) compression load cells). Inclinometers, demec gauges (50 mm and 250mm gauge length), dial gauges and strain gauges are available for data measurement. Heavy equipment, which included electrical folk lift with 1000 lbs capacity, air compressor with 10 kg/cm2 capacity, impact wrench, magnetic hand drill, hack saw machine and drilling machine are also available in the laboratory.

Some of the structural element tests were shown in the following figures.
