Fire resistance of timber-concrete composite slabs

Non-linear Analysis of Orthotropic Composite Slabs in Fire

In this study an orthotropic slab finite element is developed to model orthotropic slabs in fire, using a layered 9-noded iso-parametric slab element and a 3-noded beam element. The element is assembled from a solid slab element which represents the continuous upper portion of the profile, and a special beam element which represents the ribbed lower portion. An equivalent width for the cross-se...

FEM models of composite timber-lightweight concrete floor systems

Paper presents the main principals in designing wood-lightweight concrete composite floor structures using FEM models. All design-related analyses are performed by means of the FEA COSMOS/M program. Paper emphasises some important details in FEM model design (how to choose appropriate finite elements for different types of materials, how to connect concrete slab and timber beams to work togethe...

Behavior of Composite Timber-Concrete Beam with CFRP Reinforcement

Resistance Factor for the Design of Composite Slabs

6.1. General Probability-based design criteria in the form of load and resistance factor design (LRFD) are now applied for most construction materials. The design requirements have to insure satisfactory performance of structures. The main advantage of the approach is the ability to achieve a uniform level of reliability for structural members, or to impose a certain level of reliability (highe...

Reliability of Existing Concrete Structures during Fire – the Case Study of Concrete Slabs Subjected to Chloride Induced Corrosion

The assessment of the reliability of concrete structures during fire is becoming increasingly important due to the emergence of performance based design codes, the increased interest in decision making with respect to life time optimization of infrastructure, and the direct applicability of reliability calculations for insurance purposes. Most recent studies on the topic of the probabilistic ca...
