Data are related to the multi-objective optimization process applied to the building materials to obtain high energy-efficient precast walls for cold climate. The methodology has been explained on the paper entitled "High performance precast external walls for cold climate by a multi criteria methodology" (Baglivo and Congedo, 2016) [1]. The modeFRONTIER rel.4.3 optimization tool has been used ...

The Precast Concrete Industry (PCI) is one of the major contributors to the national economy and can be categorised as labor-intensive industry. It is currently experiencing shortcomings in terms of delivery products at a competitive cost and time. This is mainly due to the inefficiencies associate with planning and scheduling of skilled operators within crews configurations. This paper present...

Productivity estimation is a crucial task for construction managers and general estimators to efficiently allocate the required resources in order to minimize the construction costs. There is a lack of research in terms of productivity modeling for precast erection process. Therefore, this study was designed to develop a model based on Artificial Neural Networks (ANN) to predict the installatio...

the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...

Precast concrete material suppliers are responsible for the components that they manufacture from casting until up to 25 years after installation. To effectively manage the production and storage at a the production facility, to streamline the construction process and to quickly repair a component should there be a problem, information about components must be readily available and updated thro...

Devising the most appropriate testing strategy and conceiving a mock-up “as simple as possible, but not simpler” is the challenge which has to be taken whenever a research programme does involve experiments. Optimizing the experimental programme reduces the risk of either wasting time and resources or missing some of the fundamental ingredients of the structural behaviour because of oversimplif...

In the precast structures, optimization of structural elements is of great interest mainly due to a more rationalized way that elements are produced. There are several elements of precast prestressed concrete that are objects of study in optimization processes, as the prestressed joist applied in buildings slabs. This article inquires into cost minimization of continuous and simply supported sl...

Previous research has highlighted the efficacy of the application of lean production principles in the precast concrete industry. The work also highlighted the dependence of engineered-to-order prefabrication in construction on both engineering and on process control information for production in construction. In current practice in most precast/prestressed plants in the US, producers typically...

This paper intends to evaluate the feasibility of reintroducing recycled concrete aggregates in the precast industry. The mechanical properties of self-compacting concrete (SCC) with incorporation of recycled aggregates (RA) (coarse recycled aggregates (CRA) and fine recycled aggregates (FRA)) from crushed precast elements were evaluated. The goal was to evaluate the ability of producing SCC wi...

The structural integrity of precast concrete buildings depends mainly on the connections between the precast structural components. Large precast concrete panels are used extensively in North America for low, medium, and highrise construction due to their ease and speed of assembly, and high quality control. This paper presents the results of twenty-two prototype specimens tested to investigate...
