Shoring successive floors is at present the most frequently used technique when constructing reinforced concrete (RC) building structures. This technique allows the recently poured slabs to be supported by the lower slabs by means of shores. Considering the particular characteristics of shoring successive floors, it is very important to be able to estimate how loads are transmitted between shores and slabs in order to maintain adequate structural safety and avoid situations of risk or even collapse in buildings under construction. The transmission of loads from shores to slabs during all the construction stages is a complex phenomenon and has been the subject of numerous studies, especially in recent years. The research carried out to date has included experiments on full-scale buildings and the development of advanced numerical models, the estimation of the loads acting on slabs during construction, the definition of simplified calculation methods to estimate loads on slabs and shores during building construction and estimating the appropriate construction times taking into account the evolution of the mechanical properties of early-age concrete. This paper was conceived in order to give an answer to: 1) advances in the field of constructing RC building structures, 2) the growing interest of the scientific community, and 3) the need for the structural and construction engineering sector to have the tools available to increase the safety and design of building construction processes. The paper is unique in the field of RC building structures in that it is the widest, most complete and most ambitious review carried out to date and includes the most important advances in the study of slab-shore load transmissions. This work will be of interest 2 to researchers who wish to go deeper into the field of building construction, and to more experienced professionals who require all the up-to-date information in a single document. However, engineers, architects and builders could also find the paper an excellent guide that will help them to improve their daily work in the field of designing and constructing buildings.

“…In the equation (10), we set A 1 as the area of distributed reinforcement parallel to the truss bar within the range of slab width F and set β 1 as the ratio of the elastic modulus of the reinforcement in the composite beam to the concrete of the composite slab, and t is the thickness of the composite slab. rough equation (10), the automatic detection of component design results is completed.…”

“…Second, there is no standardized and uniform information standard in the eld of architecture, which makes it impossible to realize information integration and sharing among di erent application systems [8]. In the design of the projects, construction operation, maintenance of engineering projects, utilization of natural resources, usage of eco-friendly materials, and sustainable energy play important role [9][10][11]. erefore, the project developers attempt to use newer technologies, which are environment friendly and can certainly add the factor of sustainable energy for impacting the environment positively.…”

The sustainable design that can consume minimal energy is the need of the hour. It has become a mainstream architectural design aim in recent years as a result of global environmental concerns. In light of global climate change, sustainable development is imperative to consider during architectural designs of the buildings and mega infrastructural projects. All the nations are developing assembly building tools widely to speed up the construction, but the material and design impact a lot, while we calculate the environmental factors such as carbon emissions. Assembly building component automation system is often used to complete components processing and to deliver the best project, which considers environmental concerns. The construction processing involves many factors such as carbon emission, energy consumption, waste management, and solar-based energy generation to make the overall project sustainable for energy. Therefore, this paper proposes a BIM-based (Building Information Modeling) assembly building component automation system targeted at adopting sustainability principles in the construction sector, which can consider various factors for maintaining eco-friendly environment. The BIM model of the assembled building components is designed and tested in a simulated environment. The system test result shows that the error rate of component design in this system is lower than that of the other two automation systems taken up for the comparative study and the proposed process is more stable, faster, and eco-friendly. Therefore, the design result of the assembly building component automation system based on BIM technology is scientific and effective for sustainable development.

“…Für die Weiterentwicklung der Berechnungen hin zu ganzheitlichen 3D‐Gebäudemodellen müssen die Auswirkungen jedoch detaillierter erfasst werden. In [10] wurde dafür eine sehr detaillierte Abbildung gewählt, bei der die Schalung und die Unterstellungen mitmodelliert werden. Dabei wurden auch unterschiedliche Reihenfolgen und Zeitpunkte des Entfernens der Schalung sowie der Unterstellung untersucht.…”

3D‐Gebäudemodelle sind heutzutage ein weit verbreitetes Werkzeug für die Tragwerksanalyse in der Praxis. Die ermittelte Lastverteilung mittels 3D‐Gebäudemodell unterscheidet sich allerdings mitunter deutlich von den Ergebnissen einer konventionellen Berechnung mit extrahierten 2D‐Teilmodellen. Hintergrund ist, dass im 3D‐Berechnungsmodell die Verformungskompatibilität im Gesamttragwerk abgebildet wird, während die damit einhergehende Umlagerung bei einer Berechnung mit extrahierten 2D‐Teilmodellen vernachlässigt wird. Am Beispiel eines repräsentativen 15‐stöckigen Stahlbetonhochhauses mit Flachdecken und aussteifendem Kern wurden daher verschiedene Modellierungsansätze untersucht, um daraus allgemeine Empfehlungen für die praktische Anwendung von ganzheitlichen 3D‐Gebäudemodellen zu entwickeln. Dieser Beitrag zeigt zunächst auf, inwieweit sich die linear elastisch ermittelte Lastverteilung mittels 3D‐Gebäudemodell von jener einer Berechnung mit extrahierten 2D‐Teilmodellen unterscheidet. Hierbei werden zudem die Einflüsse aus der Baugeschichte, der Boden‐Bauwerk‐Interaktion, der Steifigkeiten der Anschlüsse und der Steifigkeitsreduktion der Decken durch Biegerissbildung dargestellt. Weitere Einflüsse auf die Lastverteilung in einem ganzheitlichen 3D‐Gebäudemodell infolge des zeitabhängigen Verformungsverhaltens von Beton (viskoelastische Betrachtung) werden in einem weiteren Beitrag der Autoren diskutiert. Insgesamt resultieren aus den verschiedenen Einflüssen signifikante Änderungen in der vertikalen Lastverteilung, die bei der Praxisanwendung von 3D‐Gebäudemodellen zu beachten sind.
