Quantitative estimation of mechanical characteristics soils and determination their behavior using in-situ experiments have always been one the main concerns geotechnical engineers. So far, various methods introduced to achieve this goal, among which Dynamic Cone Penetrometer (DCP) test has become more popular as most accurate efficient methods. Therefore, in study, an attempt was made examine correlation between different soil parameters by performing DCP along with a series conventional...

Monorail bridges play an important role in urban transportation networks, and their proper seismic performance is issue of great concern earthquake-prone countries. Seismic isolation a strategy that protects the from dynamic forces by increasing natural periods. Despite widespread use base conventional bridges, there are very limited reports on this technique monorail bridges. The can also be useful for straddle-type systems. This study aims to investigate nonlinear Qom Bridge (QMB), which...

The main factor for the amplification of ground motions near crest or toe a slope is reflection incident waves. effects topography on surrounding lands over at can amplify seismic responses buildings. This study investigates performance and three mid-rise buildings (five, ten, fifteen-storey) located by 3D numerical analysis. nonlinear model was used to represent real behavior building elements. average results seven records were in investigations. Based analysis, acceleration most effective...

It is essential to know the topography–soil–structure interaction (TSSI) for buildings adjacent slopes. In present study, seismic response prediction of two midrise located in vicinity slopes was evaluated using 3D numerical simulations examine effects topography–structure–soil–structure (TSSSI). The performance slope topography without any and responses a single building (TSSI cases) near crest also simulated. This study includes nonlinearity both soils (through elastoplastic hysteretic...

Buildings have different seismic responses in the topographic-soil–structural interaction (TSSI) conditions from those soil–structural (SSI). This study utilizes 3D numerical analyses to investigate of three midrise buildings with 5, 10, and 15 stories vicinity slope crest. Nonlinear behavior for soil building components was considered. Seven earthquake records perpendicular were applied models, results provided based on average records. Results indicated that topography doubled acceleration...

Abstract The occurrence of vibrational energy exchange between neighboring buildings via soil is a well‐known issue today as structure‐soil‐structure interaction (SSSI) problems. Furthermore, the seismic performance near slopes considering topography‐soil‐structure (TSSI) entirely different from their on flat grounds soil‐structure (SSI). Therefore, this study evaluates response three moments resistant frame steel with 15, 10, and 5 stories using dimensional numerical analysis new...

The reflections of waves collide with the slope, and reduction in ground lateral stiffness areas near slope crest affects buildings. In this research, using three-dimensional simulation, seismic response midrise reinforced concrete buildings located vicinity slopes was investigated. nonlinear soil behavior simulated an isotropic hardening elastoplastic hysteretic constitutive model, i.e., model small-strain (HSS). inelastic for building components considered hinges. Results were presented as...

In this paper, the effect of a group sand columns in loose soil bed using triaxial tests was studied. To investigate geotextile reinforcement type on bearing capacity these columns, Vertical encased (VESCs) and horizontally reinforced (HRSCs) were used. Number sixteen independent finite element simulation performed specimens with diameter 100 mm height 200 mm. Specimens by either single column or three same area replacement ratio (16%) to evaluate Influence arrangement. Effect number length...
