5. Example I-1 Composite Beam Design Given: A series of 45-ft. span composite beams at 10 ft. o/c are carrying the loads shown below. Design a typical floor beam with 3 in. DESIGN OF COMPOSITE BEAMS-II 2.7 Composite Trusses (7) Consider a steel truss acting compositely with the floor slab (Fig. Composite Construction and Design Introduction Composite construction refers to any members composed of more than 1 material. Examples are: Timber and … Without significantly increasing the slab depth and weight compared to those of composite slabs with typical span, it was found that these long span slabs showed good performance under the load tests. Keywords: composite slab, partial composite action, Eurocode 4, numerical analysis 1. Commentary: High concentrated loads, diaphragm loads, etc. Figure 3 - Examples of d eckin g used in composite slabs. The concrete has f′c = 4 ksi. Design of composite slabs with profiled steel decking: A comparison between experimental and analytical studies ... Download full-text PDF Read full-text. • Become familiar with detailing and design considerations for openings, penetrations, and slab depressions in composite beams. CE 433, Fall 2006 Slab Design Example 1 / 6 Design a one-way slab for an exterior bay of a multi-story office building using the information specified below. Round slab thickness up to the nearest ¼”. Typically, the building is constructed quickly with significant savings due to the use of long-span composite deck slabs, when the slabs were designed efficiently. 18 gage composite deck, and 4½ in. Calculations utilizing procedures prior to the criteria are presented at the end of the example. INTRODUCTION Corrugated iron, the ancestor of today's profiled sheet was patented as early as 1829. 2. 2.8 Longitudinal shear in composite slabs 2.8.1 The m-k or shear-bond test 2.8.2 The slip-block test Chapter 3 Simply-supported Composite Slabs and Beams 3.1 Introduction 3.2 The design example 3.3 Composite floor slabs 3.3.1 Resistance of composite slabs to sagging bending 3.3.2 Resistance of composite slabs to longitudinal shear Four long span composite slab specimens of 20 ft span length, using two different types of deck profiles, were built and tested experimentally. The beams are ASTM A992 and are unshored. The design of long-span composite slabs takes more time and effort, but the extra work is well rewarded in the final result—a modern building with large, open interior spaces. normal weight concrete above the deck, for fire protection and mass. Plan View of Floor System Assume partitions will not be damaged by deflections. The enclosed example is presented to demonstrate the intent and use of the AISI "Tentative Recommendations For The Design of Composite Steel Deck Slabs," and hereafter will be referred to as the criteria. 8).Bracing members can be generally eliminated in the central part of the span, so that – if needed – large Slabs shall be designed as simple or continuous spans under uniform loads. view of composite slab behavior and design according to EC and its critics discussed. Design Deck and Concrete as a Composite Unit 5.1 General: The composite slab shall be designed as a reinforced concrete slab with the steel deck acting as the positive reinforcement. Download full-text PDF. require additional analysis. Further attention is paid to undergoing research approaches. The parts of these composite members are rigidly connected such that no relative movement can occur. • Gain a thorough understanding of the strength and Practical Implementation of Composite Floor Designs • Gain an understanding of some common design and detailing challenges associated with composite design.
