Abstract

The purpose of this study is to describe the effect of Reduced Beam Section in vierendeel panel element in STFsystem’s inelastic behavior based on earthquake load analysis. STF system is applied to 4, 6, and 10 storey building thatserved as office building. The structure’s system used Special Moment Resisting Frame (SMRF) system in longitudinaldirection (W-E) and STF system in transversal direction (N-S). The analysis method that used in this study is nonlinearpushover analysis. Application of RBS in vierendeel panel element showed that by the increasing of storey number, theductility of the structure was increased in both directions, while N-S direction has bigger ductility than W-E direction.Dissipation energy of the structure was also increased, especially in N-S direction. The first yielding process occurred invierendeel panel element, and then followed by truss and diagonal chord around vierendeel panel element, while the criticalcondition showed still at life safety level

Abstract

A multi-level modeling and simulation method of structural system using grid-computing framework is proposed in this paper. Two levels of parallel processing will be involved in this framework: (1) multiple locally distributed computing environments connected by the local network to form (2) a grid-based cluster-to-cluster distributed computing environment. To successfully perform the simulations, a large-scale structural system is decomposed into the simulations of a simplified global model and several detailed component models with various scales. These correlated multi-scale simulation tasks are distributed amongst clusters and connected together in a multi-level modeling and simulation method and then coordinated over the internet. This paper also presents the development of a grid-computing software framework that can support the proposed simulation approach. The architectural design of the program also allows the integration of several multi-scale models to be clients and servers under a single platform. Additionally, the comparison result between proposed method and assumed exact solution show that the proposed simulation method is appropriate to simulate the response of the structural systems.

Abstract

This paper describes the finite element procedure for modeling cold-formed steel bolted moment connection to simulate hysteretic moment-rotation behavior and failure mode. The connection element consists of CFS curved flange beams, double-lipped channel columns, and trough plates. Abaqus software is used in this paper. The modeling procedure includes material properties, bolt modeling, boundary conditions, mesh, loading, and geometrical imperfections. The results of the finite element modeling were compared with the experimental test results in the form of a back-bone of the moment-rotation curve and a comparison of failure deformation. It was found that the finite element results had fairly good accuracy in predicting the hysteretic moment–rotation behavior. In the elastic region, the result shows that the finite element model successfully simulates the initial stiffness of the referenced beam-column connection. Meanwhile, the peak moment of the finite element model occurs at the same rotation as the experimental test but the magnitude of the peak moment is lower than the experimental result, which indicates that the finite element model produces a more conservative design. The comparison of failure deformation between finite element model and experimental test shows a very good agreement. The numerical model can simulate well the rotational behavior of the beam-column connection and can predict the general shape and location of local/distortional buckling at the beam-column connection.

Abstract

This study investigates the seismic performance of slit link configurations using wide-flange (WF) sections within eccentrically braced frames (EBFs), addressing the limited application of slit geometries in practical steel construction. The objective is to evaluate the influence of slit shape and width on shear strength, ductility, and energy dissipation, while ensuring damage localization within the link element. Six analytical models were developed, including conventional links (CV and CV-ST) and slit variants (SL-1 to SL-4), and analyzed through nonlinear finite element simulations in ABAQUS under the AISC 341-22 cyclic loading protocol. The analysis focused on stress distribution, hysteretic response, backbone curve stability, and energy dissipation. Results show that conventional links provide higher peak shear strength and energy absorption but transmit stresses into adjacent members, increasing repair complexity. In contrast, slit links confine plastic deformation within the link region, enhancing ductility and repairability at the expense of reduced strength. Among the slit variants, the parabolic slit (SL-4) demonstrated smoother stress redistribution and improved cyclic stability compared to rectangular slits. The novelty of this research lies in embedding slit geometries directly into WF profiles, offering a cost-effective fuse mechanism that bridges theoretical slit damper concepts with real-world EBF applications.

Abstract

Infiltration is an essential parameter in runoff, although its simulation remains challenging due to soil heterogeneity and complex structures. As soil moisture increases, infiltration capacity decreases nonlinearly, stabilizing when saturation is reached. Therefore, this study aimed to improve and validate the Horton Equation using field observations to determine infiltration capacity in watersheds. Overland flow observations were used to assess simulation accuracy from the previous studies, the sensitivity curve number was obtained at a range of 49–57. The results showed that high precipitation saturated initial losses and infiltration capacity, producing a greater runoff coefficient. The sensitivity curve numbers were obtained differently between Pandantoyo sub-basin (CN 49–53) and Ngadirejo sub-basin (CN 53–55). From modification runoff coefficient values (dimensionless,) for an ungauged catchment, it could be obtained function of f (R24, Sm), LU. Soil moisture value between Pandantoyo and Ngadirejo sub-basin was 3,562. It was also discovered that C was Q from AWLR observation and time of concentration, which influenced water discharge. A longer Tc led to lower discharge without increasing water levels. Furthermore, SCS Direct runoff method had minimal impact on runoff coefficients.

Abstract

Meteorological drought is one of the hydrometeorological phenomena that frequently occurs and has the potential to cause serious impacts on water availability, agricultural activities, and the sustainability of community livelihoods. This condition requires a deeper understanding of drought patterns as well as the capability to anticipate the likelihood of future drought events. This study aims to analyze the spatio-temporal dynamics of meteorological drought in the Blega Watershed using the China-Z Index (CZI) at multiple time scales, namely CZI-1, CZI-3, CZI-6, CZI-12, and CZI-24, while also mapping areas vulnerable to drought. In addition, this study develops drought forecasting using the Autoregressive Integrated Moving Average (ARIMA) model to estimate future drought trends. The results indicate that the CZI is capable of capturing fluctuations in drought conditions from wet to dry categories across different time scales and identifying areas with varying levels of drought vulnerability within the Blega Watershed. Time series modeling shows that the SARIMA (0,0,0)(1,0,1)12 model provides the best predictive performance, with a Mean Absolute Error (MAE) value of 0.599, indicating that the model is reasonably accurate in representing drought dynamics. These findings suggest that drought patterns in the study area are influenced by annual seasonal variations closely related to rainfall distribution. Therefore, this study not only provides a scientific overview of meteorological drought characteristics in the Blega Watershed but also offers valuable information for drought mitigation planning, water resource management, and more responsive policy-making toward climate variability.

Abstract

The rockfall hazard in areas such as mountainous regions, quarries and mines needs to be well managed. This is essential in order to avoid fatalities, damage to infrastructure and production losses. Preventing all rockfall events is almost impossible, but the installation of rockfall protection systems is a common and effective way to control the hazard. The installation of wire-meshed net anchored is a possible solution to prevent slippage of landslide of the surface layers. This paper will be focused on the study of numerical modeling, using finite element analysis software, ABAQUS, of double-twisted hexagonal wire-meshed net anchoraged which has been developed by the French-based company, GTS. The objective is to analyze several configurations and performances of wire-meshed nets, cables. As final result, we will comparing between the experiment and numerical modeling analysis.

Abstract

This study addresses the seismic vulnerability of a critical hospital in Lamongan, Indonesia, built using outdated codes. The novelty lies in using Nonlinear Time History Analysis (NLTHA) to evaluate site-specific retrofitting for healthcare facilities. By integrating Fluid Viscous Dampers (FVD’s), the research assesses inelastic structural responses under Imperial Valley, Loma Prieta, and Northridge records. Results show that FVD’s reduce base shear by 39.83% in the X-direction and 66.8% in the Y-direction. Despite higher mode effects at mid-levels, the system successfully curbs the top floor whipping effect by 29.12%, safeguarding sensitive medical equipment. For future research, it is recommended to implement nonlinear FVD modeling and life cycle cost analysis to further optimize seismic protection. These findings demonstrate that FVD retrofitting is essential for ensuring post-earthquake hospital functionality, providing a robust framework for upgrading high risk infrastructure in seismic prone regions.
