Structural efficiency of tapered tall buildings has been well recognized, and many tall buildings of tapered forms have been built throughout the world. Tall buildings are built with an enormous amount of building materials. As one of the most efficient structural forms for tall buildings, the contribution of tapered forms to saving structural materials coming from our limited natural resources could be significant. Structural design of tall buildings is generally governed by lateral stiffness rather than strength. This paper systematically studies the structural efficiency of tapered tall buildings in terms of lateral stiffness. Tall buildings of various heights and angles of taper are designed with different structural systems prevalently used for today’s tall buildings, such as diagrids, braced tubes, and core-outrigger systems. The heights of the studied buildings range from 60 to 100 stories, and the corresponding height-to-width aspect ratios in their non-tapered prismatic forms range from 6.5 to 10.8. The angles of taper studied are 1, 2, and 3 degrees. Gross floor area of each building of the same story height is maintained to be the same regardless of the different angles of taper. Based on design studies, comparative evaluation of the various structural systems for tapered tall buildings is presented.

Magnesium alloys are considered for building materials in this study due to their natural immunity to corrosion in alkaline concrete pore solution. But, chloride ions attack often hinders the application of most metals. Therefore, it is necessary to conduct a preliminary corrosion evaluation and attempt to find an effective way to resist the attack of chloride ions in concrete pore solution. In our study, hydrothermal treatment is carried out to modify Mg-9.3 wt. % Al alloy. After the treatment in NaOH solution for 10 h, scanning electron microscopy (SEM) reveals that a layer of dense coating with a thickness of about 5 μm is formed on Mg alloy. Energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and X-ray Diffraction (XRD) are combined to analyze the coating, and it is thereby confirmed that the coating is mainly composed of Mg(OH)2. As expected, both immersion test and electrochemical corrosion test show that the coated magnesium alloy has a better corrosion resistance than the uncoated one in simulated concrete pore solution with and without chloride ions. In summary, it indicates that hydrothermal treatment is a feasible method to improve the corrosion resistance of Mg alloys used for building engineering from the perspective of corrosion science.

Passive buildings can achieve energy saving goals through their own spatial form, envelope, building materials and structural design. However, at present, there are many problems in the development of passive buildings in China, such as inadequate foundation, unreasonable passive design, which make the development of passive buildings have many obstacles, not conducive to the promotion of the construction industry. Therefore, this paper analyzes the obstacle factors of passive buildings and puts forward reasonable solutions for reference.

Carbon fiber is composed of carbon atoms bonded together to form a long chain. The fibers are extremely stiff, strong, and light, and are used in many processes to create excellent building materials. Carbon fiber material comes in a variety of "raw" building-blocks, including yarns, uni-directional, weaves, braids, and several others, which are in turn used to create composite parts. The properties of a carbon fiber part are close to that of steel and the weight is close to that of plastic. Thus the strength to weight ratio (as well as stiffness to weight ratio) of a carbon fiber part is much higher than either steel or plastic. Carbon fiber is extremely strong. It is typical in engineering to measure the benefit of a material in terms of strength to weight ratio and stiffness to weight ratio, particularly in structural design, where added weight may translate into increased lifecycle costs or unsatisfactory performance.

This paper highlights wetting measurements and results carried out on four different generally used construction and some insulating materials, executed in our Building Physics laboratory in University of Debrecen, Faculty of Engineering, Debrecen, Hungary. The measurements focused on the initial state of the water up-takin procedure (240 min wetting) only, waiting for the equilibrium moisture content was not a goal of this paper. Currently, Aereated concrete, small solid brick, Porotherm and ceramsite-concrete structural members are usually applied in building structures. The measurements of water sorption investigations are so significant from the point of view of thermal sizing of the buildings. To put it simply this article can be imagined as a short time wetting sorption database comparing with our previous results, besides this article can be very useful for everyone in building physics and in building engineering. In addition building materials, insulating materials were tested and will be put forward, as well, eg.: expanded polystyrene, extruded polystyrene, poly-urethane, and some fibrous materials. Totally, 11 materials were investigated, after drying in a Venticell 111 type desiccator apparatus at 343 K to changeless weight and then wetting in a Climacell 111 type climatic chamber, where the relative humidity was varied from 25% to 95% at 293K for 240 min. As result, new isotherm curves for this short time wetting will be presented and will be compared to the literature data, MSZ-04-140-2-1991.

today energy saving and energy efficiency improvement in Russia are priority directions of the country’s energy policy. First of all, when creating an energy-efficient house, it is necessary to think about preventing heat losses through enclosing structures, and only then about reducing lighting costs, optimizing the work of building engineering systems, and the introduction of alternative energy sources. Materials for thermal insulation, the most important characteristic of which is the thermal conductivity, do the main role in the provision of optimal conditions of indoor air. The creation of thermal insulation solutions with improved thermal protection properties is a very acute problem at the moment. In this connection, the purpose of this work was to create effective compositional binders that contribute to the reduction of the density of thermal insulation materials. Within the framework of the energy-saving program and the development of housing construction of the Russian Federation and the implementation of the Federal Law №185-FZ “On assistance to the reform of housing and communal services”, the creation of new effective building materials with high performance and thermal protection characteristics that can compete with foreign analogues is of great importance. This article presents new approaches to improve the efficiency of dry heat-insulating mixtures, taking into account the law of affinity structures, which provides for the design of composites using fillers and composite binders of reduced density. Thermal insulation solutions on the basis of dry construction mixtures have superior technology, physical and mechanical and operational performance.
