In this study the fire test was performed to investigate mechanic behaviors and failure patterns of precast normal weight concrete (NWC) lightweight (LWC) walls with three types commonly used steel connectors, namely dry (61), wet (81), bearing (56E) connectors. For LWC wall specimens, on lateral application tension, cracking load values dry, wet, bearing-type connectors were 95.1%, 86.3%, 83.0...

calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. the upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. in this paper formulation of finite element limit analysis is introduced ...

this research examines the behavior of soil-reinforced piles and applied loads based on the analytical method and by using the numerical results of flac3d software for comparison with the analytical results. the analysis was based on a method called virtual retaining wall, the following into consideration: an imaginary retaining wall that passes the footing edge the bearing capacity of footing ...

SuperCritical Water Oxidation (SCWO) process is investigated at the Institut of Technical Chemistry, ITC-CPV. The objectives were to determine destruction efficiencies of model compounds and industrial waste effluents and to study the feasability of the SCWO process. Two continuous SCWO bench scale plants are operated: a pipe reactor and a transpiring wall reactor system (design data: T = 630 °...

The expression of endothelial cell (EC) adhesion molecules involved in leukocyte-vessel wall interactions is suppressed in malignancies. In the present study, we investigated in vivo the regulation of leukocyte-vessel wall interactions by the presence of a tumor. By means of intravital microscopy, tumor necrosis factor alpha-stimulated leukocyte-vessel wall interactions were studied in ear skin...

Recent work showed that polygalacturonate (pectate) chemistry controlled the growth rate of the large-celled alga Chara corallina when turgor pressure (P) was normal (about 0.5 MPa). The mechanism involved calcium withdrawal from the wall by newly supplied pectate acting as a chelator. But P itself can affect growth rate. Therefore, pectate chemistry was investigated at various P. A pressure pr...

This paper aims to investigate the combined effects of working condition and structural parameters groove texture on dynamic characteristics, stability unbalance response a water-lubricated hydrodynamic bearing–rotor system avoid instability excessive vibration rotor. The Navier–Stokes equation, standard K-? model with enhanced wall treatment Zwart–Gerber–Belamri cavitation are considered using...

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...

The article touches upon the comparative analysis of bearing system calculations a multi-storey residential building with site cast reinforced concrete frame and shear wall constructed by two different methods. In calculation models, walls are from in first case, three-layer sound thermal insulating panels second. have been made considering impact seismic force. According to results, dynamic pa...

Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...
