With the continuous improvement of building energy-conservation requirements, both traditional concrete external insulation and internal have been unable to meet energy-saving needs. In order demands in new era, precast external-wall-insulation technology should be developed. this study, a bending static test numerical simulation were carried out evaluate influence thickness inner wythe length ...

At present, with the adjustment of the structure of the steel industry, the steel logistics industry is also engaged in integrating. Steel logistics resource integration is an important problem to be solved. Based on previous research on steel logistics resource integration, this paper proposes a new research perspective on steel logistics resources integration: supply-demand network of steel l...

In this paper, a new ALC panel connector was proposed. It has good engineering economy and high fault tolerance. A quasistatic loading experiment carried out to verify the feasibility of external steel frame under seismic loading. The test phenomena, hysteretic curve, skeleton stiffness degradation, energy dissipation two sets full-scale specimens were analyzed discussed. Moreover, simulation p...

Ferrous metals include cast iron, steel, and the various steel alloys, The only difference between iron and steel is the carbon content. Cast iron contains more than 2-percent carbon, while steel contains less than 2 percent. An alloy is a substance composed of two or more elements. Therefore, all steels are an alloy of iron and carbon, but the term “alloy steel” normally refers to a steel that...

The high performance obtained in wet mix sprayed concrete has extended the field of applications of this technique. In some of these applications, such as in diaphragm walls or bridge rehabilitation, the structure may be subjected to bending moments, so conventional reinforcement is regularly used. In this context it is important to assure adequate bond between steel rebar and the sprayed concr...

This paper presents the mechanical properties of high strength structural steel and mild structural steel at elevated temperatures. Mechanical properties of structural steel at elevated temperatures are important for fire resistant design of steel structures. However, current design standards for fire resistance of steel structures are mainly based on the investigation of hot-rolled carbon stee...

Electrochemical Impedance (EIS) experimental data recorded on an intentionally inflicted scribe on Q-steel coated panels exposed in a laboratory environment was analyzed using equivalent electrical circu it-analog model technique for the corrosion-inhibition performance. The sand-blasted steel panels were pre-painted with a non-chromate industrial epoxy primer having dispersed corrosion-inhibit...

Since the rubber units are mostly standardized in the industry, the real engineering and, design challenge is with the steel panels, chains and the corresponding anchorage. The rubber unit is a crucial component of the system, but is only as good as the overall design of the system. SFT has inspected numerous systems of even reputable fender manufacturer, that showed signs of premature failures...

Industrial CT (computerized tomography) uses a series of 2-dimensional images taken at specific intervals around the entire sample. Basically any type of industrial CT system uses three principal components: an X-ray tube, an X-ray detector, and a rotational stage. Everything is enclosed within a radiation shielding steel/lead/steel cabinet that typically ranges between four and 10 feet cubed. ...
