This research investigates the nonlinear behavior of scaled infilled masonry (IFM), confined (CM), and reinforced concrete (RC) structures by utilizing validating two tests from literature as benchmarks. The validation was based on a comparison with pushover results small-scaled physical their numerical modeling. Numerical modeling small-scale (1:4 1:3) IFM, CM, RC models has been carried out F...

Unanchored steel storage tanks are used in industrial plants to store oil and other petrochemical liquids. In a major earthquake, such may sustain different types of damage, including elasto-plastic buckling the shape an elephant's foot, which is object research. The methodology introduced this paper consists cloud-based 1D site response analysis (SRA) pushover-based seismic performance assessm...

This paper compares the target displacement estimate from four current nonlinear static procedures—FEMA-356 CM, ASCE­ 41 CM, ATC-40 CSM, and FEMA-440 CSM—with the value derived from recorded motions of five strongly shaken reinforced concrete buildings.This comparison provides useful insight into two important questions: (1) how much does the target displacement vary among the four nonlinear st...

The prototype hybrid high-rise structure is special for its dual structural systems, so a 1/50 shaking table model was tested by the State Key Laboratory of Disaster Reduction in Civil Engineering of Tongji University to study its seismic behaviors. Then numerical models were made by 3D finite element analysis software, named MIDAS. The comparison of the analytical and experimental results veri...

an adaptive version of growing and pruning rbf neural network has been used to predict the system output and implement linear model-based predictive controller (lmpc) and non-linear model-based predictive controller (nmpc) strategies. a radial-basis neural network with growing and pruning capabilities is introduced to carry out on-line model identification.an unscented kalman filter (ukf) algor...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...
