This could lead to debonding between the mortar layer and the track slab. Based on the theory of viscoelasticity and the analytical method of the time hardening law(THL), the viscoelastic deformation behavior of CA mortar was studied. Using ABAQUS, we established a solid model of China railway track system(CRTS) Ⅰ prefabricated slab track, with CA mortar at different initial Young’s moduli under cyclic loading corresponding to the influence of actual train loads. The results reveal that the fitted parameters of the THL for CA mortar are suitable for describing its viscoelastic deformation. As the initial Young’s modulus increases, the strain difference before and after cyclic loading gradually decreases, and the displacement difference increases from 0.2 mm to 0.6 mm. The deformation mainly occurs at the end of a mortar layer with longitudinal distribution of about 2.5 times the fasteners’ spacing. It follows that the viscoelastic performance of CA mortar is one of the most important reasons that cause debonding underneath the track slab. Therefore, we suggest that the adverse effects of viscoelastic behavior of CA mortar should be considered when researching such deformation and damage.展开更多

Significant damage can occur to sections or components of units during these operations. Although damage usually will not impair its structural safety, it is costly to fix and causes the public to perceive prefabricated wooden buildings as low quality products. Field observations and preliminary numerical models for prefabricated units subject to lifting and transportation forces are summarized here. Once fully developed and verified, models will support the creation of damage mitigation strategies centered on structural details indicating how units are to be supported during lifting and transportation.展开更多

The cross-border integration of construction and IT is BIM technology, and the emergence of BIM technology provides new ideas for prefabricated building, and the integration of prefabricated building and BIM technology realizes the construction industrialization. This paper studies the application of BIM technology in prefabricated buildings, including the design phase, construction and assembly phase, operation and maintenance phase, and application analysis of related software, so as to improve the high efficiency, high quality and high precision development of prefabricated projects, and promote domestic green environmental protection. The development of the construction industry provides reference value for the application of BIM technology in prefabricated buildings.
文摘Old-age building was designed in Ziwu Town,from the aspects of energy saving,environmental protection,full use of solar energy and characteristics of the local climate.In order to meet the requirements of energy conservation,environmental protection and climate adaptability of residential buildings,this paper integrates the construction and design in the prefabricated building design,at the same time,with the consideration of the possibility of expansion and removal of the nursing home,the concept of "modular unit" is put forward.Considering the climatic adaptability of the base position,the utilization of solar energy and the organization of natural ventilation should be paid attention to,also,the rammed soil construction method is added in this design,which can improve the thermal insulation performance of the building enclosure and create a comfortable indoor thermal environment both in winter and summer.In order to realize the object of industrial building construction and design,the prefabricated construction method is used,which produces impact on the surrounding environment more environmentally friendly.The building will be easily built,less restricted,and low-cost.What's more,local material and the advantages of all dry work increase the operability of the project.
