This paper presents a study on flexural behavior of unbonded post-tensioned concrete T-beams (UPC) externally strengthened by CFRP sheets under static loading with or without the presence of U-strip CFRP anchorage systems. A total of nine UPC T-beams in large size including one control unstrengthened beam and eight beams externally strengthened with varied number of CFRP sheets (2, 4, and 6 plies) were tested. Two types of transverse CFRP U-strip anchorage system were also retrofitted in the shear span. The results showed that CFRP sheets significantly increased the flexural capacity (up to 37%), decreased deflection in serviceability state, improved ductility, and reduced crack width (up to 48%) of the tested beams. The maximum strain in CFRP sheets in strengthened UPC T-beams ranged from 38.7 to 69.3% of the rupture strain of the CFRP sheets and tended to decrease with a large number of CFRP sheets. Strain in tendons of strengthened beams was significantly affected by the CFRP sheets and transverse U-strip anchorage system.

Socio-economic growth in Vietnam greatly depends on the new rural development process in this country; the work is considered a strategic position in national development. Thus, the study of the principles of the architectural design of new rural housing solutions in accordance with the New Rural Environment as required by the Vietnam Ministry of Construction has become urgent. Climate change has become a global concern, so the creation of significant impacts by architectural designs to respond to climate change and make the living environment of rural people better is a major demand. Experience has shown that the dogmatic application of current urban-type housing does not reach the requirements of New Rural Housing. This research intends to show that the solutions of the traditional Vietnamese rural house, which retains the advantages of traditional architecture with excellent characteristics that have been challenged over thousands of years, when combined with advanced design methodologies and technologies, will be the appropriate solution for 'New Rural Housing

Internet vạn vật (Internet of Things - IoT) là nền tảng công nghệ đê xây dựng thư viện điện tử đáp ứng các yêu cầu của cách m ạng công nghiệp 4.0. IoT làm thay đổi quan điểm trong việc lưu trữ, tiếp cận, kết nối và xử lý dữ liệu trên thư viện điện tử. Từ đó, tác động đến hoạt động xây dựng các yếu tô' cấu trúc, tổ chức các dịch vụ dành cho bạn đọc và thiết lập quy trình, phương thức quản lý nghiệp vụ của thư viện điện tử.
