A reporter raises concerns about the underestimation of bending moments in perimeter columns when assessing punching shear in adjacent concrete slabs. Punching shear failures can be brittle and catastrophic. Designers need to include the appropriate ultimate moment in the design actions.

This report describes a situation where site testing of post-installed fasteners in concrete was undertaken by a contractor as an alternative to adopting the design data from the manufacturer in an attempt to justify an increased design capacity for the fasteners.

This report highlights the importance of verifying technical data provided by the manufacturer or supplier of proprietary products.

This report highlights that water ingress into buildings continues to be a problem and discusses the role of the structural engineer when dealing with waterproofing of exposed concrete slabs. It shows how this can be achieved by careful design and detailing of the reinforced concrete structure and by close collaboration of all parties involved.

This report highlights the importance of correctly designed fixings and anchoring systems for cladding panels to buildings to minimize the risk of failure.

This report highlights the risk of failure if grouted joints between load-bearing prefabricated concrete members are not designed and installed correctly.

This report draws attention to the requirement for internal partitions to be designed for horizontal loads from wind and seismic effects in accordance with Section B of the Australian National Construction Code (NCC).

During construction of steel structures with composite metal decking floors, a reporter has observed numerous occasions when the metal decking was close to being overloaded.

While working on construction sites a reporter was involved with tower crane bases supported on piles with pile caps and pedestals with cast-in anchors that had significant construction defects.
