In general, the thermal insulating material is that thermal coefficient is less than or equal to 0.14W/(m-K), with good heat preservation performance and is widely used in the field of industrial and construction. This paper introduced the main kinds of thermal insulation material, summarized the research...

In this research a traditional house and a comfortable house are chosen, their thermal environment including air temperatures, air relative humidity, and surface temperature of walls are tested, and test result are analysed. In addition, the thermal advantages and shortages of these two houses are summarized,...

Based on the hypothesis of neglecting tensile strength of concrete when concrete beam is bended, the simple bending concrete cover of four-point bending concrete beam is cut, thus forming a " -shaped" notch on the side elevation of the beam. Such beam is called a wide notch concrete beam, which is a...

To analyze and summarize the actual characteristics of retaining wall under different circumstances, which include nature soil, soil in different degree of compaction and soil with anchors, a finite element model is established according to an expressway widening project, which includes a gravity retaining...

Although various studies and hundreds of laboratory experiments related to the punching shear strength of reinforced concrete (RC) slabs have been published and conducted respectively, code provisions have been developed based on a rather limited subset of the available test results and those studies...

Foundation design of high-rise buildings in karst region is always the difficult point of ground treatment in a construction project. In order to ensure the stability of the foundation, the foundation and ground of high-rise building need to be strengthened in karst area. According to the characteristics...

A large number of ground motions were obtained during recent great earthquakes such as the 2008 Wenchuan earthquake and 2011 Tohoku earthquake and some of them present double-plateau features, this paper focuses on the identification and spatial distribution of double-plateau ground motions. First, the...

Intermediate crack debonding failure is one of the most common failure modes in the FRP reinforced concrete structures. In order to simulate the formation of debonding failure accurately, this paper adopts an elastic-plastic damage constitutive law to model concrete and take into account the interface...

Water conservancy project generally has the characteristics of long running time and under high pressure and high flow rate and large flow, the director of the valve outlet exist cavitations and other issues, and the body vibration is more serious, the situation on the valve work. This paper based on...

For building the mathematical model of force and stress on the interference fit surface of composite back-up roll by the shrinkage fit method, the roll sleeve and roll mandrel was studied respectively. The loads acted on the contact zone was discretized and the roll sleeve and roll mandrel were discretized...

The design spectra for vertical earthquake action in the new version of guidelines for seismic design of highway bridges of China is presented in this paper. The spectra are stipulated with the same formula, same figure as the horizontal one, but different parameters in another parallel table. The parameters...
