1. Course Objective

Transverse openings in concrete beams represent, from a practical viewpoint, a means of accommodating utility services in a building structure. The ability to accommodate such services through a member instead of below or above the member results in a compact design and an overall saving in terms of total building height.

Provision of openings through a beam however changes its simple mode of behavior to a more complex one. Therefore, the design of such beams needs special treatment, which currently falls beyond the scope of the major building codes.

The objective of this course is to provide the state-of-the-art information on the behaviour, analysis and design of concrete beams that contain transverse openings through the web. The behaviour of such beams under bending, shear and torsion will be treated in this course. Design methods based on plastic hinge mechanism, plasticity truss and strut-and-tie models, and skew-bending theory are described and illustrated with numerical examples. Suitable guidelines on the detailing of beams with web openings will also be discussed. These information would not only give valuable guidance to the designers and consultants of concrete structures but also would help researchers in the planning and proper execution of future research programs in this area.

3. Target Audience

Practising engineers and designers who wish to deepen and broaden their knowledge, thereby enhancing their design capabilities, researchers and teachers involved in the field of structural concrete, and professionals from public works, building and transportation authorities who are involved in decisions regarding the construction and maintenance of concrete structures. The participants should have some background of the analysis and design of reinforced concrete.
