Structures Laboratory

Located on the 2nd floor of Davis Hall, the structures laboratory is anchored by a 41 ft. x 131 ft. concrete strong floor with a 10 ton bridge crane which can accommodate test specimens up to 17 feet in height.  This test facility is used to study the behavior of structural elements and systems, on both scale models and prototypes. Cameras 1 and 2 show real-time view of the 2nd floor test area.

A large-scale, inverted concrete bent cap was tested during December 2013 on the east end of the 2nd floor test facility in Davis Hall for Prof. Khalid Mosalam’s graduate student Mohamed Aly Moustafa .  The objective of this test was to investigate the structural behavior and effective width of integral bent caps in reinforced concrete box-girder bridges.  The test program includes two large-scale (1/4 scale) column-superstructure subassembly. The specimen geometry and dimensions were adopted from a typical California bridge and designed according to the latest AASHTO and Caltrans provisions. This first test used bidirectional cyclic loading and constant gravity load. The second test will consider Hybrid Simulation testing methods to test the specimen under bi-directional earthquake loading. Both tests aim at investigating the structural behavior of bent caps under both gravity and lateral loads, and the contribution of the box-girder to the bent cap stiffness. 

Additionally, we have a full Machine Shop and are able to create specialized test fixtures and instrumentation. Depending on the size, we may be able to even fabricate your test specimen from your specifications.

(For CEE students only:

All CEE students have regular access to the Mechanical Engineering Student Access Machine Shop.  CEE students may use this shop for class and research projects.  The Mechanical Engineering Student Access Machine Shop is an educational facility that has as its goal the training of students in the principles of machining.  This facility provides training for students in basic machining as well as general access for project work.  Use of this facility is a great opportunity for CEE students to gain hands-on shop experience in an educational facility.  The facility includes basic equipment such as lathes, mills, and drills, along with more advanced tools, such as abrasive jet cutting tools.

The CEE professional shop is still available for professional/research projects and those projects that are beyond the capabilities of students.

To utilize the Mechanical Engineering Access Student Access Machine Shop, you need to complete a safety orientation course.  Contact Scott McCormick, Student Access Machine Shop, 1166 Etcheverry Hall, at mccormick@berkeley.edu or 642.4006.

Mick Franssen, Dennis Lee and Jesse Lopez handle the preliminary five hours safety orientation, which is broken down into four phases, with an exit exam at the end. )

The various subsections below describe our full capabilities in more details. For specific test needs or to develop a test plan, please contact the CEE Technical Staff (Shakhzod Takhirov, 510.642.4309) .
