Glass Embedding: Safe and Fast Glass Embedding Solution for Glass BalustradesEric Black
A brief Vertical Glass overview including Structural Silicone applications, SikaTack®-Panel Bonding and Sika's compatible systems. Focus on the benefits of using SikaGlaze® GG-735 (SikaForce) on glass embedding applications vs. traditional systems. Metering and Dispensing Equipment for mid to large size jobs.
This article presents the analysis and design of troughed floors. These are slabs that combines the advantages of ribbed floors with those of a slab with level soffits (flat slab). They provide one of the most efficient solution for long-span floors, typically up to 12m and are also very effective where good surface finish is desired. The levelled soffits present the floor with the advantage of exposing the slab profile which may be used for passive cooling or for aesthetics. They are composed of very shallow beams spanning between columns with typically equal depth narrow ribs spanning in the orthogonal direction. A thin slab layer known as the topping completes the system. Overall, they tend to be dipper than solid or flat slabs but are considerably lighter in weight than an equivalent flat slab, thus the extent of their foundations is greatly reduced. This paper therefore, aims to introduce the concept, analysis and design of troughed floors to the reader. Also, a practical workedexample using the Eurocode has been included in this article to aid the reader in further understanding the design of this kind of floors.
Bridges with hinged spans after a centenary experienceDCEE2017
Pier Giorgio Malerba.
Several steel and R.C. continuous bridges of the last century were made statically determinate by
placing hinge connections in suitable points of their spans (articulated bridges). The main
advantages of this choice are a clear and simple static scheme and the avoidance of spurious effect
due to settlements of the foundations.
On the other hand, the systematic use of bearing supports and joints along the spans causes slope
discontinuities of the road platform: under the permanent loads, such kinks are progressively
increased by shrinkage, creep and steel relaxation effects; under the traffic loads these local
discontinuities foster the dynamic effects in the neighbourhood of the hinges and causes severe
damages both at these devices and at their interfaces with the body of the main structure. Moreover,
these effects are an inconvenience as far as the appearance of the structure and ride comfort.
This contribution would present an overview of the performance of these bridges after a century of
experiences and to highlight their most diffused drawbacks. Particular attention is paid to the hinge
connections made of a couple of opposite R.C. corbels, which is one of the most critical zones. In
fact, their shape made difficult the detailing of the bars, frequently quite congested, attracts and
retains the damaging agents (salted water from the platform) and, as a consequence, gives rise to
fast corrosion states. Some criteria for their structural assessment are given and the examples of
rehabilitation are presented.
