“…Secondly, we should establish an interactive mechanism and adhere to the concept of cultural education. Based on the integration and interaction of university cultural construction, coordinating development direction, strengthening the interaction and integration of different majors, and promoting coordination and reference between disciplines to realize the cultural construction and development of universities in the form of cultural interaction assisted by each other is vital (Zwicky and Vogel, 2006 ).…”

After the reform and opening up in China, through a series of rapid developments in world, online education has grown both socially and economically. This area has become representative of the fast-growing economy. However, Guangfu culture as a crucial component of Cantonese traditional culture is gradually becoming less influential today. It is the college's responsibility and duty to protect, carry forward, and inherit this traditional culture. Especially during this cyber era, where networks have become a powerful source for communication and study, there are diversified methods of adaptive learning and various learning behaviors. This article aims to analyze the plausibility of adapting an online platform into the teaching arena and the needs of students under this teaching mode. A simulation of applying advanced technology and artificial intelligence into Guangfu culture innovation was also conducted. The contribution shows the users in this platform have a longer study time, compared with non-platform users, and are more interested in traditional culture knowledge than non-users; 21.5% higher in the performance's test.

“…At ultimate state, the cracks in concrete have developed seriously, so concrete compression softening effect should be considered. The diagonal compression capacity of concrete can be represented by effective compressive strength f ce , which can be approximated as f ce = 1.6 f c 2/3 , and f c is the uniaxial compressive strength of concrete (Zwicky and Vogel, 2006). The JEAC 4618-2009 regulations have suggested a formula for calculating the concrete diagonal compression capacity, and accordingly in this study, the controlling value for concrete strength can be expressed as…”

Steel–concrete–steel composite structure comprises a concrete core sandwiched between the outer steel plates. It combines the advantages of both steel and reinforced concrete structures. In thick steel–concrete–steel structural members, the shear performance becomes rather critical. Experimental works have been carried out to study the failure mode and shear strength of steel–concrete–steel deep beams, and an analytical model has been proposed. In this article, parametric studies are carried out on the original analytical model to discuss the influence of each geometric and material variable on the shear strength, and a simplified strength predicting method is developed. Different shear failure modes, identified as “top+bottom triangular area damage” or “bottom triangular area damage+horizontal cracking,” can be predicted with the method. The simplified approach shows good correlation with the experimental results, regarding to shear resisting pattern and failure modes. Through the simplified formulas, the upper and lower bounds of the shear resistance are obtained. The requirement on stud spacing to maintain full composite behavior in the top and bottom triangular areas and the requirement on concrete strength are proposed.

“…In this case, concrete strength in the diagonals has to be chosen depending on principal strain as well as bond between diagonals and stringer reinforcement has to be controlled [7].  Use stress fields instead of strut and tie models, which cover also the required depth of the struts, proper anchorage of the ties and limited stresses in the nodes.…”

Switzerland can be seen as an example of an industrialized and densely populated European country. Its national highway network gets old, and therefore assessment, upgrading and refurbishing of highway structures like bridges become an important issue. At first, these three terms are questioned, replaced by more meaningful ones and a superior single term is proposed. Then the main steps to keep an infrastructure in good shape are explained. Special emphasis is placed on the different formats to verify the structural safety of an existing structure and preceding procedures like the updating of data. Anticipation of future needs and considerations on the network level will become more important and have consequences for decisions on the optimal intervention. Three recent examples illustrate the general statements.
