Protective Technology (PE) Laboratory, CEE

Designed for carrying out dynamic load testing of full-scale structural components, the Protective Engineering (PE) Laboratory located in the School of Civil & Environmental Engineering was ready in year December 2001.

With a high headroom, the PE Laboratory will have a 30m×30m strong floor area, together with a system of L-shaped reaction wall with multi-cell design. Test facilities will include a shake table and dynamic actuators of various capacities. This integrated facility has been designed to carry out cyclic loading tests and pseudo-dynamic tests of large- or full-scale structural components.

Construction Technology Laboratory, CEE

Occupying a 60m×24m strong floor with a 10m headroom, the Heavy Structures Laboratory located in the School of Civil & Environmental Engineering is the largest structural testing laboratory in Singapore.

The Laboratory is well equipped with state-of-the-art hardware and software for analytical, experimental and field investigations. Facilities for testing structural components and materials include sophisticated fatigue testing machines, a 5,000 kN capacity Schenck-Trebel universal testing machine, and test rigs for full-scale multi-planar tubular structural steel joints.

Fire Engineering Facilities, CEE

The facilities are available for column testing and for cruciform testing under elevated temperature.

The column test facility (Figure 1) includes the test rig, electric furnaces, and the loading actuator. The test rig is designed with movable reaction girders, which are suitable for test specimens between 1.6 to 4.2 m long. The actuator has the capacity of 5000 kN, and the electric furnace can generate heat of up to 900 degree Celsius.

The cruciform test facility (Figure 2) includes 5 m3 electric furnace, portal frames, and reaction frames. The portal frames and the reaction frames are designed for 1000 kN capacity hydraulic jack, for vertical and horizontal loading applications, respectively.

Split Hopkinson Pressure Bar, CEE

The 75 mm diameter Split Hopkinson Pressure Bar (SHPB) facility has been designed and developed to meet research needs related to protective engineering. A series of data acquisition and data storage facility is integrated with the SHPB. Specialised software for data analysis and a modified striker bar (impactor) have been developed to provide the tools to support further research and contract testing of construction and brittle materials under impact.

Strenght of Materials Laboratory, MPE

	Lansmont Model 23 Cushion Test System, This special equipment is used to test different type of cushion materials and designs over various conditions under both drop and static loading. The ballast kits start from 1.02 kg to 14.5 kg and the maximum equivalent free fall drop height is 1.52m. It can hold a specimen of an area up to 23x23 cm2		A pneumatic gun with 50 mm and 22 mm diameters exchangeable smooth bores. The maximum pressure is 160 Bars. The gun has the capacity of firing up to 4 kg mass at 220 m/s, that is, the kinetic energy of approximately 100 kJ. The velocity is much higher for smaller projectiles. The performance of the gun can be enhanced by extending the length of the launch tube.
	Compression Hopkinson Bar, Tension Split Hopkinson Bar and Torsion Hopkinson Bar for measuring the effect of strain rate on the mechanical properties of materials. The bars can be used to help characterise the mechanical properties of metals, polymers, as well as concrete and rocks.		A drop hammer with mass ranging from 10 to 100 kg and impact speed of approximately 6 m/s. The maximum energy available is approximately 36 kJ.
