“…Although most of the papers have focused on LCA methodology, some provide results allowing to give impact results, especially outside the most widespread climate change. Thus, according to Marzouk et al [26] study, "manufacturing and transportation off-site phase represents the highest weight of ozone-depleting particles with 92.83% while deconstruction and demolition phase's largest contribution is in eutrophication particles". Some difficulties in evaluating reuse impact with LCA are due to several uncertainties such as full use of lifespan, the number of use cycles, reconditioning operations, resulting in a lack of data [40].…”

“…Load-bearing systems represent the most substantial part of EE [24,25], with 39% according to Marzouk et al [26], and 50% and above of the total building embodied impact also called embodied carbon for Kaethner et al [27] and Veselka et al [28]. As such, foundations and structural elements are mainly part of the building to improve in order to decrease the EC [25,26]. Thus, among the various stakeholders, structural engineers have a decisive role in the environmental impact of buildings [26,29] and must master life cycle assessment (LCA) to reduce this impact judiciously.Reuse in construction can potentially target around three billion tons of raw materials worldwide, representing significant economic interests, around 40-50% of the total flow of the world's economy [18].…”

The reuse of load-bearing components over several building life cycles [30] is a promising avenue for meeting the environmental challenges facing the construction sector [31].…”

In a context of intense environmental pressure where the construction sector has the greatest impact on several indicators, the reuse of load-bearing elements is the most promising by avoiding the production of waste, preserving natural resources and reducing greenhouse gas emissions by decreasing embodied energy. This study proposes a methodology based on a chain of tools to enable structural engineers to anticipate future reuse. This methodology describes the design of reversible assemblies, the addition of complementary information in the building information modeling (BIM), reinforced traceability, and the development of a material bank. At the same time, controlling the environmental impacts of reuse is planned by carrying out a life cycle assessment (LCA) at all stages of the project. Two scenarios for reuse design are applied with the toolchain proposed. A. "design from a stock" scenario, which leads to 100% of elements being reused, using only elements from stock. B. "design with a stock" scenario, which seeks to integrate as many reused elements available in the stock as possible. The case study of a high-rise building deconstructed to rebuild a medium-rise building demonstrated that the developed toolchain allowed the inclusion of all reuse elements in a new structural calculation model. Sustainability 2020, 12, 3147 2 of 24 the largest exploiters of natural resources [8], accounting for between 40% of the total raw materials consumption [9] and 50% [10].This growing development has repercussions on the emission of GHGs, among other indicators. In France, the construction and building industry is the leading emitter of GHGs [11], i.e., 33% of total GHGs. Several studies confirm this number worldwide [6,12,13]. Kumar Dixit et al. [8] define the embodied energy (EE) and embodied carbon (EC). EE during the construction phase is the amount of energy used for the extraction of raw materials, the production and transport of building components as well as the building construction and end-of-life (EOL). Moreover, EC refers to the associated GHG emissions [3]; the operating energy during the operation phase as energy consumption and associated operational carbon emissions during the use phase of buildings (heating, cooling, etc.). The average value of EE is 50% of the total primary energy demand [14]. The share of operational energy seems to decrease recently (even disappearing in passive or zero energy buildings) with technical progress and, therefore, the share of EE increases [15].Another impact of the construction sector is due to waste generation [5,16]. Most of the literature focuses on waste management, which shows a great interest in reducing the construction and demolition waste (CDW) generated by the construction sector as it represents around 40% of the waste produced [17]. Cai et al. [18] and Lismont et al. [19] explained that in Europe, about 25-30% of the waste result from the building sector amounting to 870 million tons annually and Brütting et al. [3] estimated this share at more than a third ...

The 'pile-wall interaction' is a new foundation technology in geotechnical engineering and it has not been widely used in the structure design, neither at home or abroad. Besides, the corresponding domestic design specifications are still relatively lacking, which leads to a huge difference of design in different regions. Therefore, the authors pay attention to analysis and summary of the project about 'pile-wall interaction' from different countries and areas in the world, and point out some problems about this emerging technology. They hope that this study can promote the application and development of 'pile-wall interaction' technology.
