Abstract

According to UU No. 28 of 2002 concerning Buildings (UUBG), the reliability of school buildings needs to be ensured to accommodate the learning activity of students and teachers. This issue should be a great concern, especially for special schools. This community service program aims to help non-productive communities access reliable learning facilities through visual audit assistance. The community service program consists of four stages, namely the inventory of school buildings technical data, document inspection, visual audit, and reports of audit result. The results of this community service are a report of SMPLB-A YPAB buildings condition, a report of visual audit results, and dissemination of visual audit results. This community service supports SDG 11, Sustainable Cities and Communities, particularly in the improvement of environment quality and inclusive communities within the context of school building.

Abstract

The use of Reinforced Concrete (RC) deep beams in the building may require web openings or holes for electricaland mechanical utility passage. This web opening will change the behavior of the RC deep beam and may result in early crackseven at service load. Hence, it is important to use a suitable tool to predict the full response of the RC deep beam with theopening. For that purpose, a nonlinear finite element method using 3D-NLFEA software package which utilizes a plasticityfracture model is used to predict the behavior of RC deep beam. One deep beam specimen available in the literature isinvestigated. To study the effect of using structured and unstructured mesh, as well as different element types on the loaddeflection curve, the hexahedral and tetrahedral solid element was used. From the comparisons, it was observed that the crackpattern between two different meshes was not similar. Structured mesh often has straighter crack propagation compared to theunstructured mesh. The load-deflection curve for both models is similar and both models were performed satisfactorily inpredicting the peak load of the deep beam.

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 evaluates the seismic performance of steel moment-resisting frames through the integration of reduced beam sections (RBS) with externally reinforced cover plates. Three-dimensional finite element analyses under cyclic loading were conducted to assess the influence of cover plates on different RBS geometries, including radius cut (RBSCP-RC), straight cut (RBSCP-SC), tapered cut (RBSCP-TC), and drilled flange (RBSCP-DF). The objective of this study is to investigate the effects of geometric variation on seismic response, moment capacity, and ductility of hybrid RBS–cover plate (RBSCP) connections. The novelty of this research lies in the systematic development and evaluation of a hybrid RBS–cover plate connection that combines the energy dissipation capability of RBS with the strengthening function of cover plates. This configuration is intended to shift plastic hinge formation away from the column face, reduce the risk of premature weld failure, and improve connection strength and energy dissipation. The numerical results indicate that the incorporation of cover plates significantly enhances the seismic performance of RBS connections, with the radius-cut configuration demonstrating the most stable hysteretic behavior and the highest energy dissipation capacity. These findings emphasize the importance of geometric optimization in hybrid RBS–cover plate designs and provide valuable guidance for improving the seismic resilience of steel moment-resisting frames.

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.
