Abstract

Currently, BIM has been widely applied in structural design and construction management work. However, there has not been much BIM implementation in evaluating existing structures. Thus, BIM was implemented in this study to evaluate the structural capacity and seismic responses of low-rise buildings due to earthquake loads. The case study was conducted on the Pakubuwono X Mosque building, designed in 2017 based on SNI 2847:2013, SNI 1726:2012, and SNI 1727:2013. This research was carried out numerically by involving the interconnection of Autodesk Revit and Autodesk Robot SAP software, which worked within the BIM framework. The structural model of the Pakubuwono X Mosque building was developed using Autodesk Revit, which was connected to Autodesk Robot SAP for analysis and structural design processes. Furthermore, the design products of Autodesk Robot SAP are reconnected with Autodesk Revit to be integrated with architectural and MEP (mechanical, electrical, and plumbing) design products. In this study, the structural capacity evaluation was carried out on the floor slabs, beams, and columns. Furthermore, the seismic response in the form of modal participation mass ratio, fundamental period, base shear, and story drift are also reviewed in this study. In conclusion, all structural elements (floor slabs, beams, and columns) are adequate to support the design load as indicated by the demand-capacity ratio (D/C Ratio), which is less than 1.0. Furthermore, all parameters of seismic response reviewed in this research comply with the requirements set out in SNI 1726:2012.

Abstract

Earthquake-resistant structures are vital to achieving sustainable buildings as they minimize damage during seismic events and allow for easier repairs. In contrast, non-engineered buildings (NEBs) often suffer severe damage, contributing to waste that burdens the environment. Many residential buildings in Indonesia fall into this NEB category, so evaluating the extent of damage during earthquakes is essential. This study analyzed the seismic response of NEB using Incremental Dynamic Analysis (IDA). The dynamic pushover curves derived from the IDA were further examined to identify the damage limit states pertinent to NEB, considering the randomness of the ground motions. The proposed damage limit states, categorized into various levels (DS1-DS4) and their corresponding uncertainties due to random ground motions, highlight the vulnerability of NEBs to seismic events. The high probability of damage to NEBs makes stakeholders aware of the need to take measures to improve the resilience and, ultimately, the sustainability of residential buildings.

Abstract

The background of this research is that plastic waste is abundantly available around us and has not been optimally utilized. Pedestrian which is also the right of pedestrians with disabilities has not been well organized in Indonesia. The use of plastic waste materials is an alternative to solving environmental problems. The utilization of plastic as a substitute for cement will also reduce the carbon effect of cement as a building material. With its light weight when compared to disabled terrazzo tiles on the market, it is hoped that it can facilitate the application of smart pedestrian blocks as pedestrian paths and disabilities. The purpose of this research is the utilization of plastic waste as used as composite thermoplastic waste brick as well as an alternative eco friendly material. The experimental method used normal paving, 45% plastic waste, 55% plastic waste, and 65% plastic waste. The test results show that the average compressive strength for paving with 45% plastic waste has a compressive strength of 9.16 MPa higher than normal paving which is only 8.56 MPa. This shows that the use of 45% plastic waste as an effective substitute for cement in paving is also an environmentally friendly solution. In addition to reducing plastic waste, it also reduces the need for cement.

Abstract

The sustainability of local road construction projects plays a critical role in the achievement of long-term environmental, social, and economic development goals. This study aimed to assess the sustainability level of local road construction projects using a structured sustainability index. The research employed a mixed-methods approach, combining a comprehensive literature review, stakeholder engagement, and the Delphi technique to determine relevant sustainability indicators and assign appropriate weightings. The sustainability index was tested and validated by means of an expert evaluation and pilot application in selected local road projects. The findings indicate that environmental aspects tend to receive higher priority compared to social and economic aspects, mainly due to the increasing global emphasis on climate change and resource conservation. However, the study also highlights the importance of integrating social equity and local economic benefits to achieve a balanced sustainable development. The novelty of this research lies in its structured index framework tailored specifically for local road projects, supported by multi-stakeholder consensus, and its potential application in infrastructure planning and public procurement processes. This study contributes to the limited body of knowledge regarding sustainability assessments in local infrastructure development, especially in developing regions. The developed index offers a practical tool for local governments and stakeholders to incorporate sustainability principles into decision-making processes.
