ABSTRACT
Numerical computation for lower surface pressure coefficients on a porous sunshade roof cover sheet (pp. 3-9)
Dr. Vu Thanh Trung, Prof. Yukio Tamura, A/Prof. Akihito Yoshida
This paper describes a computational method that is based on the extended form of the Bernoulli equation for predicting the lower surface pressure coefficients on a porous sunshade roof cover sheet with respect to two porosities f (ratio between area of orifices and area of sheet) and various wind angles from known upper surface and surrounding pressures. The results of wind tunnel experiments on two 1:50 scale-models of low-rise buildings with porous sunshade roof cover sheets are good in good agreement with the computational results.
A study  on evaluating stability of  Red riverbank line in the Hanoi area (pp.10-14)
MEng. Nguyen Cong Kien, MEng. Nguyen Van Ta
The paper presents actuality of Red river bank unstability in the Hanoi area, analysing and evaluating acting factors leading to them. By combinaison of factors belonging to technical-natural condition, Red river bank unstability risk in the Hanoi area is predicted with 4 levels.
Effect of the confinement by reinforced bar to the compressive capacity of axial reinforced concrete column (pp.15-21)
MEng. Thai Duc Kien
Based on the theory of the confined concrete, this paper present the result of research on the effect of the reinforced bar to the compressive capacity of rectangular reinforced concrete column. The effect of the reinforced bar was defined base on former research results, and was studied by using ANSYS. The results of study was compared and evaluated.
Evaluation Method of Energy Efficiency for Buildings (pp.22-28)
MEng. Nguyen son lam
This paper presents method used for civil building energy performance evaluation. This method isused for building energy efficiency performance evaluation of all existing buildings and existing building energy retrofitting projects. The building energy evaluation in the paper addresses to building envelop thermal performance, HVAC system, lighting system and renewable energy utilization. Building energy efficiency evaluation of existing buildings, existing building energy retrofitting projects shall not only comply with this method, but also comply with other concerned building regulations.
Dipterocarpus latex motar brick masonry (29-35)
Ba. Hoang Ngoc Hiep, Dr. Tran Minh Duc
Dipterocarpus latex motar (DL motar) is used for Restoration of Champa temples, that means: the  Champa masonry are maded from spesial brick and this special motar. Last time LAS XD – 578 have studed working ability of DL motsr in the masonry. The results are presented in this paper.
Application high performance concrete to repair top surface of hangar (pp.36-39)
Dr. Nguyen Quang Hiep, Eng. Ho Trong Manh
This paper presents results of research and application of high concrete reinforced with steel fiber dispersed in the thin layer of concrete floor repair hangar No. 2 - Noi Bai International Airport.
Influence of Puzzolan and Fly ash on some physico-mechanical properties of Roller Compacted Concrete (RCC) (pp.40-46)
Dr. Nguyen Quang Phu, MEng. Nguyen Thanh Le
To study the influences of Puzzolan and fly ash on the physico-mechanical properties of roller compacted concrete for dams project in our country. Thereby determine the appropriate type of mineral additives for roller compacted concrete dam to ensure economic and technical works.
Calculation, analysis and assessment of work horizontal displacement parameters (pp.47-51)
MEng. Tran Ngoc Dong
In this article, the author presents some contents in calculation of parameters on partial and total displacement of the work, analysis and assessment of confidence level of displacement parameters of monitoring points and application of graphics software to represent displacement development of the monitoring points and entire work to enable us to have brief and detailed understandings of displacement process of the work.
Applying fire dynamic simulator (FDS) software to survey and evaluate buildings structures fire damaged (pp.52-58)
Eng. Hoang Manh, Eng. Ha Van Hanh, Eng. Nguyen Viet Son
Fire dynamic simulator softwares are often used in the study fire safety solutions for buildings, and also can be used to analyze changes in the development of fire to support fire assessment survey based on the actual factors of the buildings: such as fire load, characteristics of geometry of combustion chamber, ventilation conditions, etc. This text introduces Fire Dynamic Simulator (FDS) software which is now widely adopted around the world and is also being applied in the Department for Fire Safety Engineering - Institute of Building Structures. The authors present the results obtained through analysis of a realworld project.
