Nonlinear Axisymmetric Vibration of Sandwich FGM Shallow Spherical Caps with Lightweight Porous Core - Trang 381-389 - 2022
Minh, Tran Quang, Dong, Dang Thuy, Duc, Vu Minh, Van Tien, Nguyen, Phuong, Nguyen Thi, Nam, Vu Hoai
This paper presents the axisymmetric vibration responses of sandwich Functionally graded material (FGM) shallow spherical caps with lightweight porous core subjected to uniformly external loads and shell-foundation Pasternak interaction. Based on the first-order...
Geotechnical Properties of Hai Phong and Ninh Binh Clays in the Red River Delta - Trang 751-758 - 2020
Phuc, Tran Thi, Giao, Pham Huy
Nowadays, many infrastructures are increasingly and continuously developed all over the Red River Delta (RRD), which is founded on a soft clay deposit of low strength and high compressibility. In this paper, geological and geotechnical data were collected at two...
Simulation of Concrete-Filled Steel Box Columns - Trang 359-366 - 2020
Pham, Duc-Duy, Nguyen, Phu-Cuong, Nguyen, Duy-Liem, Le, Hoang-An
Concrete-Filled Steel Tube Columns (CFSTC) are applied widely in civil engineering, special in bridge structures, because of their high ductility and strength. As observed, local buckling effects significantly affect on the limited strength of the columns, the cause...
Effect of Carbon Nanotubes on the Chloride Penetration in Ultra-High-Performance Concrete - Trang 69-80 - 2021
Hao, Pham Manh, Tuan, Nguyen Van, Thang, Nguyen Cong, Thao, Nguyen Van, Hai, Luong Nhu, Dong, Pham Sy, Man, Nguyen Xuan, Thuy, Ngo Ngoc
The improvement of Carbon Nanotubes (CNTs) addition on the properties of concrete has been recently investigated, e.g. mechanical properties and durability, but is rarely reported for Ultra-High-Performance Concrete (UHPC) with a very low water to binder ratio. This...
Research and Development of Wind Power in Vietnam - Trang 270-275 - 2019
Phan, Anh Tuan, Nguyen, Dong, Pham, Thi Thanh Huong
This paper mentions to a research study on wind power policies and development in Vietnam. Wind energy is considered as a green energy source, clean and inexhaustible. This energy is not depleted but the only problem is how much percentage of this energy we can...
