Cellulose insulation was introduced into Korea in the 1980s when several small companies started production. The cellulose industry in Korea is still in an early stage of development with current production of about 1000 tons a year. The Korean equipment used to produce cellulose insulation was imported...

Two new type of RC beam to concrete filled steel tubular column joints are proposed here. Test study on 22 joint specimens under vertical load is introduced here, which includes RC beam to concrete filled steel tubular column joints with four types of connections and RC beam to circular column joints....

In order to test the correctness and feasibility of high strain measured curve fitting method of pile, field tests of vertical bearing capacity of pile were carried out using prestressed concrete pipe pile. The following test results can be obtained: (1) According to the actual soil layer parameters...

Reliability-based design optimization (RBDO) is a more rational optimization design method due to its consideration of the structure reliability requirements. A new RBDO-kriging method that combines kriging agent model and covariance matrix adaptation evolution strategy (CMAES) is proposed to solve the...

Based on the experimental results and theoretical analysis, the study of the classification and mechanism of the premature failure for low-grade R.C. beams reinforced with bonded steel plate is placed on, finally, reasonable measure to overcome the premature failure is introduced..

In this paper, the present situation of roof waterproof technology was discussed and the working principle and failure reasons of roof waterproof system were analyzed. Combined with the actual high-rise building project, the key technologies of roof waterproofing design and construction have been discussed...

The large - span single - layer reticulated shell structure is a structure sensitive to the load distribution. Different distribution of snow load has an effect on the stable bearing capacity of the reticulated shell structure. The unfavorable snow load distribution may cause the stable bearing capacity...

Based on the creep characteristics of the overlying Jurassic sandstone in the goaf in Yulin area of Northern Shaanxiby the RLW-2000 microcomputer controlled rock triaxial compression creep testing machine, the parameter values of Burgers creep model of the Jurassic sandstone are determined, and the creep...

Shale inhibitor has been widely used as a cure of shale dispersion and swelling when drilling in shale formation. To make clear the effect of the interaction time, type and adding order of inhibitors on the hydration of bentonite, the particle size distribution (PSD) measurements of bentonite have been...

X-ray energy dispersive spectrometer (EDS) and X-ray diffraction (XRD) tests are performed to investigate the chemical composition of Hangzhou soft clay. For comparison purposes, the above two tests are carried out on Hangzhou stiff clay. Based on EDS results, sulfur(S) can't be found in Hangzhou stiff...

After reviewing the relevant literature on green campus, this study has analyzed the current design practice. It shows that there are shortcomings in the green campus design strategies for the outdoor physical environment. There are three aspects in the shortcomings: (1) the site planning, (2) the layout...

The proper disposal of sewage sludge has been paid much attention. The traditional methods of sludge disposal include sanitary landfill, composting, thermo chemical treatment (including pyrolysis and combustion), and sea disposal. Urban sludge has the dual attributes of pollutants and resources. The...
