Program goals: - Produce graduates equipped to pursue careers in structural design and analysis in industry, the public sector and non-governmental organisations;. The span-to-width ratios are such that these bridges may be designed for simple 1-way bending as opposed to 2-way plate bending. The thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure. 92311182 Steel Code Check Theory Enu. At the interface between the slabs and the supporting masonry wall normally a crack develops. The determination of internal forces and the design is performed according to the linear analysis. 0 Design of slab according to Eurocode 2 FLEXURAL DESIGN (EN1992-1-1,cl. Partial and full shear connection can be also designed. where fcd is the design value of the cylinder compressive strength of concrete and hc is the thickness of concrete above the main flat surface of the top of the ribs of the sheeting.

There is no need to assign special data to the slab-column connection. Examples utilize a flat plate subjected to uniform load and a concrete slab on steel beams subjected to fork-lift truck loads. The floor system of a structure can take many forms such as in situ solid slabs, ribbed slabs or precast units. The design of slab-column connection is the most critical point in the design of flat slabs, because of the concentration of shear stresses in this region that can lead to punching, which is a localized failure mode that can occur without significant warnings and may lead the whole structure to ruin through the progressive collapse. The worked examples in Chapter 9 demonstrates the application of theory to design of pinned and moment resistant base plates, pinned and moment resistance beam to column connections and the use of.

On the other hand, finite element analysis using computer programs can be used. Note that design moment for slabs is calculated on a typical 1-ft wide section of the slab. This section will explain how the direct design method is used. The allowable bearing capacity for the supporting soil is 60 KN/m. Even reinforced concrete, where steel bars are used to take up the tension that the concrete cannot resist, is prone to cracking and corrosion under low loads.

The fact that the number of the tested footings is considerably lower than the number of tested flat slabs lead to the situation that, due to the similarity of the problem, for the design of the punching shear resistance of reinforced concrete footings and reinforced concrete foundation slabs take empirical expressions obtained at the punching. Since floor slabs are designed for moving live loads, the design should be checked for stationary live loading conditions. Alasdair Beal BSc CEng MICE FIStructE.

Two Way Beam Supported Slab References: 1. In the 1950s, flat slabs without capitals started to become prevalent. For flat slabs, punching may also govern. Manual for Design and Detailing of Reinforced Concrete to the September 2013 Code of Practice for Structural Use of Concrete 2013 2. This is because different models are used in different design codes to describe the punching shear capacity and different limitations are put on the stress in the shear reinforcement. Grade C is for seismic conditions or where additional ductility is required. Numerical Example: Consider a 5 m long and 150 mm thick reinforced concrete slab, fully restrained at each end. 1 Design basis 90 4. Many flat slabs are designed in an environment where the contractor should be involved. The output of the program for the slab in the example is shown in the following pages.
