Advantages of precast concrete structures were very obvious, these were the sign of industrialized construction, while also reducing costs, energy conservation, and improve quality. In recent years, the demand of precast concrete buildings was also increasing. BIM technology was advanced technology, the design of precast structures, such as the frame shear wall structure, was given by using BIM technology in the complete process; Design process and value of the application of the BIM technology in the prefabricated structure were analyzed, Prospects of the BIM technology using in prefabricated structures were discussed.

Precast concrete frame structures are widely adopted around the world due to their various advantages, so it is important to study their seismic performance. The development of damage mechanics has enabled us to accurately investigate the typical failure mechanisms of precast structures. This paper presents three of the most commonly used modeling approaches based on damage mechanics for analysis of precast reinforced concrete structures under cyclic loading and compares the performance of the three models. Particularly, the shear behavior of the joint panel and the bond-slip behavior of the beam–column interfaces are especially considered, which are the key issues for precast concrete structures. First, the fundamental assumptions, formulations, and modeling strategies are given in detail for each approach. Then, the unified damage mechanics for concrete is introduced, and the model for reinforcement bars and the consideration of the bond-slip effect are also presented. Several benchmark cyclic tests of precast beam-to-column connections are chosen to evaluate the accuracy and efficiency of the modeling approaches. The numerical results, e.g. the capacities, deformations, and energy dissipation of the connections, are compared to the experimental results to show the ability of each approach. With this study, we can gain a further understanding of the characteristics and applicability of each modeling approach, helping us make a better decision in choosing which modeling approach is appropriate.

The objective of this paper is to apply the life cycle assessment methodology to assess the environmental impacts of light steel framed buildings fabricated from cold formed steel (CFS) sections. The assessment covers all phases over the life span of the building from material production, construction, use, and the end of building life, in addition to loads and benefits from reuse/recycling after building disposal. The life cycle inventory and environmental impact indicators are estimated using the Athena Impact Estimator for Buildings. The input data related to the building materials used are extracted from a building information model of the building while the operating energy in the use phase is calculated using an energy simulation software. The Athena Impact Estimator calculates the following mid-point environmental measures: global warming potential (GWP), acidification potential, human health potential, ozone depletion potential, smog potential, eutrophication potential, primary and non-renewable energy (PE) consumption, and fossil fuel consumption. The LCA assessment was applied to a case study of a university building. Results of the case study related to GWP and PE were as follows. The building foundations were responsible for 29% of the embodied GWP and 20% of the embodied PE, while the CFS skeleton was responsible for 30% of the embodied GWP and 49% of the embodied PE. The production stage was responsible for 90% of the embodied GWP and embodied PE. When benefits associated with recycling/reuse were included in the analysis according to Module D of EN 15978, the embodied GWP was reduced by 15.4% while the embodied PE was reduced by 6.22%. Compared with conventional construction systems, the CFS framing systems had much lower embodied GWP and PE.

The paper presents a method for assessing the daylighting of premises, which can be used directly at the stage of architectural and construction design of buildings in building information model (BIM) software complexes. The calculation method is based on the calculation of the sky factor by constructing a solid angle formed by the calculated point and the light opening of the outer wall. These operations are proposed to be performed automatically using visual programming programs that work together with the BIM complexes. Since the considered calculation method is based on the idea of the physical meaning of the daylight factor, it can be used to evaluate the daylighting according to almost any regulatory method. At the same time, all the data necessary for the calculation can be obtained directly from the building information model. The method is universal and can be used both for the calculation of side and top daylighting, considering the surrounding development. The proposed method can also be used as a tool for finding the best design solution for translucent structures of the designed building based on the requirements of thermal protection, daylighting, and safety.
