Rapid expansion of developed cities create problems mainly attributed to traffic congestions. Recently, Bangkok has faced rapid growth and the expanded neighborhoods require convenient public transport to be linked with central Bangkok and other parts of Thailand. Monorails can be an exceptional alternative to conventional skylines and subways thankfully to their excellent climbing abilities, lower noise, shorter constructions periods, and their capabilities to be adapted within limited spaces. Recently, Mass Rapid Transit Authority adopted monorail system to facilitate public in Bangkok's expanding neighborhoods. A four‐span continuous posttensioned girder system has been proposed for the straddle monorail system. Current study focuses on the structural response of full‐scale precast posttensioned (FPP) end girders in the proposed monorail system. Results suggested that the girder remained undamaged under service load while exhibiting a linear load versus vertical deflection response. Failure under ultimate load was accompanied by crushing of concrete, buckling of compression longitudinal bars and posttension tendons at the midspan. Further, experimental rosette strains suggested that concrete strains remained well below the ultimate of strains in the vicinity of high shear zones of the girder. Therefore, these results augment that the proposed design practice is safe against shear and the proposed girder can safely be used as the end girder in four‐span straddle monorail system. Nonlinear analysis of the girder was performed using advanced tool for engineering nonlinear analysis by adopting its built‐in constitutive laws for concrete and steel reinforcement. Predicted analytical response of FPP was in good agreement with experimental results in terms of load‐deflection curves, crack patterns, and failure mode.

“…ATENA can analyze the actual performance of bridge structures. [22][23][24] FPP girder was analyzed using the built-in material models of steel, concrete, and other materials. Concrete and steel were modeled using constitutive laws defined by "CC3DNonLinCementitious2" and "CCReinforcement material model", respectively.…”

“…It is a finite element program developed by Cervenka Consulting to simulate the behavior of concrete structures [1]. It serves as a user-friendly tool for modeling reinforced concrete elements, facilitating the visualization of crack propagation, and providing real-time result displays, even during the performance of nonlinear analyses [2,3]. ATENA Science has been used to study various concrete structural behaviors [1][2][3][4][5][6][7].…”

The use of numerical methods in solving engineering problems can save both time and costs compared to experiments. In this study, the finite element analysis software ATENA Science was employed to model reinforced concrete columns subjected to axial compressive loads. The columns modeled in this study had previously undergone experimental compression tests. The primary objective of this modeling was to assess the compatibility of ATENA Science simulations with the experimental results. Based on a comparison between the ATENA analysis and experimental data, the ATENA analysis produced results that closely matched the experimental outcomes. In this case, the study specifically focused on the L-D relationship and crack patterns. The alignment of these results is important as it serves as validation, allowing for future modifications to the test specimens as required.

This research was conducted on the Surakarta-Gemolong-Geyer road, which is suspected to be built on expansive land. Every day, this road is always passed by large vehicles, so it is feared that it will be easily damaged if it is not routinely carried out maintenance. This study aims to analyze the damage to the rigid pavement on the highway using ATENA 3D software. The damage analyzed in this study is the deflection. The factors that make the crack large and wide were added to the heavy vehicle load and swelling. The swelling test on the soil carried out in the laboratory was 37 kPa. The results obtained after analysis with 3D ATENA showed differences in deflection at each loading variation. The variation of the middle loading with swelling pressure has a value of -15.49 mm; without swelling pressure, it is -16.37 mm. The middle loading variation with swelling and without pressure has a value of -15.33 mm and -12.4 mm, respectively. Corner loading variation with swelling and without pressure has a maximum deflection of 1.28 mm and -0.26 mm, respectively. This research can be used as a reference and prediction in identifying cracks that occur so that the government can carry out maintenance and rehabilitation before the road is damaged.
