Abstract: Exterior insulation is currently promoting a building energy-saving insulation technology. Compared with internal insulation, it is a reasonable technique and has its obvious advantages. However, in the insulation material, thermal insulation effect is better, fireproof performance is often worse. Through analyzing several external wall insulation materials’ insulation and fireproof performance, the article recommends a kind of external wall thermal insulation material with good insulation and fireproof performance, to meet the construction needs.

Abstract: Due to the continuous upgrading technology of high-rise buildings, function expansion of high-rise buildings has unlimited possibilities, in the specific performance of function system’s optimization and function model’s integration. Function expansion make high-rise buildings’ image become various with a variety of features, internal use space become more efficient, convenient, thus for mankind to create a more comfortable space.

Abstract: Proposing design principles to improve the external environment of high-rise buildings, including the principle of integrity, the principle of symbiosis, the principle of balance, the principle of environmental enhancement and the principle of economic. Specifically, a series of measures proposed to achieve good urban space of the high-rise buildings.

Abstract: Contemporary high-tech buildings pursue ecological design. Through the use of new technologies, new materials and advanced scientific means to solve ecological problems. By improving energy efficiency, reducing consumption of non-renewable resources, making full use of clean energy, architects create an ideal living environment.

Abstract: High-rise building is one type of architecture which is strongly dependent on structural technology, materials technology and equipment technology. Its emergence promoted technical innovation with ceaseless breakthrough. Contemporary high-rise buildings pursue ecological design through the use of new technologies, new materials and advanced scientific means such as structure, equipment, materials and construction methods.

Abstract: Little progress has been made in experimental studying on high-temperature mechanical properties of concrete under multiaxial compression. Triaxial proportional compressive tests of ordinary concrete after suffering to high temperature (200°C ~600°C) were carried out, the designed stress ratios are 0.1:0.25:1, 0.1:0.5:1, 0.1:0.75:1 and 0.1:1:1. The failure models of concrete specimens after suffering high temperature were observed. The biaxial compressive strength and deformation characteristics of which were measured. The influences of temperature and stress ratio were analyzed. On the basis of the analysis, the relationship between compressive strength and temperature as well as stress ratio was established in octahedral stress space.
