“…In comparison to reinforced concrete slabs, composite floor systems offer a more economical solution ( Figure 15 ) [ 186 ]. The constituent structural elements of the reinforced concrete slabs can optimize the strength and performances of the steel and the concrete as well.…”

Concrete is the most common building material; therefore, when designing structures, it is obligatory to consider all structural parameters and design characteristics such as acoustic properties. In particular, this is to ensure comfortable living conditions for people in residential premises, including acoustic comfort. Different types of concrete behave differently as a sound conductor; especially dense mixtures are superior sound reflectors, and light ones are sound absorbers. It is found that the level of sound reflection in modified concrete is highly dependent on the type of aggregates, size and distribution of pores, and changes in concrete mix design constituents. The sound absorption of acoustic insulation concrete (AIC) can be improved by forming open pores in concrete matrices by either using a porous aggregate or foam agent. To this end, this article reviews the noise and sound transmission in buildings, types of acoustic insulating materials, and the AIC properties. This literature study also provides a critical review on the type of concretes, the acoustic insulation of buildings and their components, the assessment of sound insulation of structures, as well as synopsizes the research development trends to generate comprehensive insights into the potential applications of AIC as applicable material to mitigate noise pollution for increase productivity, health, and well-being.

“…Under load, the headed studs transfer horizontal shear forces between the steel and concrete, causing the two parts to behave as if they were one composite member. The majority of studies has been done up to this point [7][8][9][10][11][12][13]15] concerned with composite construction done on a concrete slab over top flange of steel beam. The mechanical shear connectors on top flange may be considered to be either flexible or rigid in ordinary composite construction industries.…”

This paper deals with flexural investigation of a type of steel-concrete composite beam structure able to provide an adequate bond between steel and concrete elements through the application of a simple steel reinforcement shear connector design, steel reinforcing bars bent into L-shapes. The cross sections involve inverted steel T-beam being embedded within reinforced concrete (RC) flange of the slab. The paper concentrates on elastic and elastic-plastic behaviour of steel inverted T-beam entrenched within a reinforced concrete flange at the top. In addition, shear connection was investigated in detail. Finally, some suggested designing equations and curves simulating the elastic, elastoplastic and full plastic experimental moments were developed. The plastic theoretical study results coincides with the experimental behaviour of the developed model.

“…Advancements in construction materials and techniques have supported the potential for various large-span composite floors applied in building structures, such as the steeltimber composite floor [1,2], steel-concrete composite floor [3][4][5], steel-deck composite floor [6,7], cold-formed steel composite floor [8,9], steel space frame-concrete slab composite floor [10], and other kinds of hybrid composite floors [11][12][13][14]. Currently, these composite floors have been widely used in gymnasiums [15], offices [16], and airport lounges [17], which may be prone to human-induced vibrations due to their low natural frequencies and low damping ratios [18][19][20].…”

This study investigates the dynamic performance of a large-span suspended steel space frame-glass composite floor (SSSF-GCF). Both the ambient vibration and the human-induced vibration of the floor were experimentally measured to identify vertical dynamic characteristics and evaluate vibration serviceability of the floor. Although vertical dynamic characteristics of the floor based on the global simplified finite element (FE) model of the structure agree well with those identified via experimental modal analysis, the global simplified FE model significantly underestimates vertical vibration amplitudes of the floor due to the coupled effect between two layers. Accordingly, an equivalent local FE model of the floor system was proposed and updated via adjusting the vertical stiffness of the interstory hanging pillars. It is shown that the equivalent local FE model can well predict both the dynamic characteristics and human-induced vibration response of the floor. Finally, the effect of the damping ratio on the acceleration response of the floor was numerically demonstrated with the verified local FE model.
