In recent years, there are a lot of wooden houses that is needed seismic retrofitting. We have developed lattice bearing wall suitable for retrofitting tenement style house. It made 12mm structural plywood laid diagonally transparency and ventilation. this study, the performance clarified we proposed simple analysis model as result. was could accurately estimate wall.

Slewing bearing, which is widely applied in tank, excavator and wind turbine, is a critical component of rotational machine. Standard procedure for bearing life calculation and condition assessment was established in general rolling bearings, nevertheless, relatively less literatures, in regard to the health condition assessment of slewing bearing, were published in past. Real time health condi...

Schwertmannite, a kind of iron oxyhydrosulfate mineral, can removal arsenic(III) from arsenic(III)-bearing groundwater by the adsorption process. In this study, schwertmannite was bio-synthesized by Acidithiobacillus ferrooxidans LX5 in shaking flasks (160 rpm) containing a 0.16 mol/L FeSO4 liquid solution. After bio-synthesis, 25.5% of the bio-synthesized schwertmannite adhered to the reactor ...

Nowadays, in order to increase construction of tall structures, the importance choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had used as stiff high performance lateral system. This study is about effect concrete filled tubes (CFT) columns vertical boundary elements wall on...

Drilled pile foundations that have been set in hard soil are generally used for buildings with shear walls. By nature, a drilled foundation can withstand moments because of the pile’s dimensions and amount reinforcement installed. This study presents structural analysis 10-story building supported by dual system structure to meet earthquake requirements. The results show that, using system, req...

The seismic response characteristics of a lead-rubber-bearing(LRB) base-isolated structure under rare and very earthquakes were investigated. acceleration, ductility coefficient, shear strain the LRB increase significantly in comparison to earthquakes; particular, may exceed ultimate cause damage structure. criterion selected for optimum tuned inerter damper (TID) TID–LRB hybrid control system ...

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...

Currently, the exploration and development scope of Changqing oilfield has gradually developed to edge blocks deep systems, typically Yanchi block. However, in construction process, there are some problems such as poor well wall stability, frequent leakage prominent collapse contradiction, which seriously restricts increase drilling speed. In this paper, measures structure optimization, system ...
