- Description
- Composite slab construction is gaining popularity in New Zealand. These slabs may influence beam column joint subassemblies as they are exposed to earthquakeinduced shaking. However, several design issues with composite slabs need to be addressed so that they can be used to their full advantage in design. These relate to considering the effect of the slab on the beam design strength, the likely statistical variation of the beam and slab under strong seismic shocks that will affect the column joint demand, and the resistance of the panel zone.
In this paper, experimental test setups are described which consider slab isolation, beam
overstrength, full depth slab around the column, low damage connection, and demand on the panel zone. A new concept of slab confinement using a shear key will be presented to form a force transfer mechanism to avoid failure of concrete either in crushing or spalling. Also the development of a non-prying sliding hinge joint low damage connection and its performance with composite slabs is discussed. The outcome of this
will be useful to develop simple design recommendations for the New Zealand steel
standard.

- Seismic design of composite metal deck and concrete-filled diaphragms - A discussion paper

- Description
- One of the most neglected elements in the design of buildings is the horizontal floor diaphragm and its interaction with the lateral load resisting systems. Most multi-story structures depend on the floor slab and roof systems to act as horizontal diaphragms to collect and distribute the lateral loads to the vertical framing members, which provide the overall structural stability.
In steel structures, floor diaphragms are most commonly constructed using composite steel deck with concrete fill, although other systems may also be used. Somewhat surprisingly, given the importance of diaphragms to the overall building response, there is no universally agreed design procedure for determining the diaphragm actions and distribution into the seismic-resisting systems. In addition, the specific issues related to beam design for members collecting lateral loads in composite floor systems has gone largely undocumented.
This discussion paper presents a suggested method in determining the design diaphragm actions at a given floor level, how to proportion their transfer into the seismic resisting systems and how to design and detail the supporting beams/composite metal deck for these actions.

- Structure types ; Composite structures
- Description
- In the paper the heat exposure and structural response model of reinforced concrete ceiling concreted into trapezoidal sheet is analysed. Temperature within the cross-section and in reinforcement is determined on the basis of European standards for fire design of concrete structures and steel-concrete structures using available formulas. Mechanical load is stated for accidental design situation. Fire resistance is assessed for structural resistance and insulation criteria.

- Capacity of composite steel-concrete columns

- Description
- This paper studies the resistance of composite steel-concrete cross-section of columns at the ultimate limit state. The recommended design procedure is focused on solving the problem with the aid of the normal force vs. bending moment diagram, whose construction is time-consuming. This makes economical design difficult. Therefore a user-friendly application (a simple program on VBA platform) was developed for everyday use. The practical solution and some derivations are explained in this paper.
