Resumen

Mass timber floors are being used increasingly in both mass timber and hybrid timber buildings due to its dry and rapid construction. Bare mass timber structural slabs have relatively low impact sound insulation performance. Though certain floating floor assemblies on mass timber slabs can provide adequate single number ratings, such assemblies are mainly effective in the middle to high frequency range. This paper will provide an overview of the research on the impact sound insulation perforamnce of mass timber floors with exposed ceiling and floating floor assembies conducted at the Universti

Resumen

Mass timber buildings are gaining increasing popularity as a sustainable alternative to concrete and steel structures. Mass timber panels, especially cross-laminated timber (CLT), are often used as floors due to their dry and fast construction. CLT has poor impact sound insulation performance due to its lightweight and relatively high bending stiffness. Floating concrete toppings are often applied to increase both the airborne and impact sound insulation performance. However, the impact sound insulation performance of floating concrete toppings on CLT structural floors is affected by both the

Resumen

Though cross laminated timber slab floors are being used increasingly in mass timber construction, solid mass timber slab floors are limited to short-to-medium span applications. The sound insulation performance of solid mass timber slab floors is often achieved through assemblies on the floor surface as exposed wood ceilings are often prefered by achitects and occupants. A mass timber cassete floor system has been recently designed and tested for its structural, vibrational and acoustical performance.

Resumen

In the last years several projects of medium and high-rise timber-based multi-story buildings have been proposed and developed. In most of the cases timber-concrete composite (TCC) floors play a significant role for the design of the structural slabs due to acoustic performance, fire protection and structural issues. Within several research projects and with the aim to optimize the structural and ecological characteristics of building components the Department of Structural Design and Timber Engineering (ITI) at the Vienna University of Technology (TU Wien) developed timber-steel hybrid beams

Resumen

Floor vibration, although not a safety concern, is a prevalent performance complaint in multi-story structures. With the increasing use of mass timber construction, various types of long-span timber floors (LSTFs), including plain cross-laminated timber (CLT), CLT with secondary beams (ribbed-deck), and hybrid systems such as timber–concrete composite (TCC) and CLT on-steel-support beams, are gaining popularity. However, due to limited knowledge regarding their vibration characteristics and acceptance criteria, these construction types are often overlooked during the design stage by architects

Resumen

Cross-laminated timber (CLT) floors with supplementary layers or floating floors comprise a common solution in new multistory timber structures. However, bare CLT components provide poor sound insulation, especially in low frequencies during structure-borne sound propagation. Thus, floor configurations in wooden buildings deploy more layers for improved acoustic behavior. Twelve contemporary CLT floors were analyzed after laboratory measurements of airborne sound reduction and impact sound transmission utilizing the following indicators: Rw, Rw, 100, Rw, 50, Ln,w, Ln,w,100, and Ln,w,50 (per IS

Resumen

Timber-concrete composite floors can be seen as bi-dimensional elements constituted by repeatable longitudinal elements (timber beams) connected through an element capable to spread the load on the transverse direction (concrete slab). This is usually a fact to “take advantage of” in terms of design, in the light of current regulations, with the analysis of a “T-shape” beam. Nevertheless, when concerning the action of concentrated loads, considering them supported entirely by the beam to which they are applied can result in a disadvantage rather than an advantage.

Timber-concrete composite (TCC) solutions are not a novelty. They were scientifically referred to at the beginning of the 20th century and they have proven their value in recent decades. Regarding a TCC floor at the design stage, there are some assumptions, at the standard level, concerning the action of concentrated loads which may be far from reality, specifically those associating the entire load to the beam over which it is applied. This naturally oversizes the beam and affects how the load is distributed transversally, affecting the TCC solution economically and mechanically. Efforts have

Steel–timber composite beams are a relatively new type of composite structure. They have many important advantages, owing to which they may be considered a sustainable solution. Their connectors may be demountable, which makes it possible to separate steel girders from LVL panels at the end of their service life. After disassembly, the structural elements can be recycled. One of their advantages is that they are lighter than steel–concrete composite beams. However, this may result in the poor performance of floors with steel–timber composite elements subjected to dynamic loadings. For this rea

This paper presents a novel, ultra-thin topping solution where the topping is placed at a thickness of 20mm or less. Advantages of the solution include: reducing the mass added to the existing structure and minimising the change in floor to ceiling height whilst delivering a significant increase in floor stiffness.

Resumen

When impact sound tests are carried out in new and refurbished flats there is not normally a load on the floor. When the flat is occupied however, loading due to furniture, appliances, people etc, will occur which compresses the resilient layer if a floating floor construction has been used. The effect this has on impact sound insulation is considered in this paper. Impact sound transmission through a chipboard floating floor on battens supported on a concrete floor has been measured when static loads were placed on the chipboard – the loads were in the range 20 kg/m3 to 160 kg/m2.

Resumen

This article describes a project to investigate the dynamic behaviour of a prefabricated timber-concrete composite floor slab developed for the Department for Education's GenZero sustainable schools programme. The GenZero initiative involves a new building system made of a kit of parts that could be manufactured off site and then assembled on site to create diferent confgurations of secondary school. The slab is constructed of a precast concrete deck on glulam ribs, with two interlayers. The project investigated the effect of both the interlayers and different shear connectors on the performan

Resumen

Design for deconstruction (DfD) considers the end-of-life scenario of buildings at an early design stage to ensure that these buildings (or parts of the buildings) can be deconstructed without unproportional effort and material loss. After deconstruction, the elements or materials can be used for future purposes such as reusing (preferably), remanufacturing, or recycling. This opinion paper is aimed to advocate for DfD in timber–concrete composite (TCC) floors as it represents an important contribution toward circular economy design and creates a more sustainable built environment.

Resumen

In recent years, there has been an increasing interest in timber–concrete composite (TCC) floors as a sustainable structural solution. Until now, only a few studies have investigated the demounting of TCC floors, which is essential to increase sustainability and improve the end-of-life environmental benefits of a floor system. This study investigates an innovative and straightforward demountable TCC slab that has notched and bolted connections. Six downscaled slabs are tested under four-point bending. The results show that the slab system has high composite action with an efficiency of 0.73. A

Resumen

The behavior of cross-laminated timber (CLT) and reinforced concrete (RC) floors in a multi-story building is investigated in this paper. The load-bearing capacity, fire resistance, and sound insulation characteristics of the floors are the main focus of this research. In order to achieve this goal, a four-story building having RC floors is modeled, analyzed, and designed using the StruSoft FEM-Design software (FEM) following the Eurocodes and Swedish national annex. The building is considered to be in the city of Gävle in Sweden. Then, the RC floors of the building are replaced with the CLT f
