Analysis Behaviour of Podium-Type Buildings with Special Moment Resisting Frame (SMRF) and Dual System Using the Spectrum Response Method

2025-04-29T17:22:03+07:00

The design of the building structure has undergone considerable changes so that it needs to be considered more for the calculation of earthquakes. Earthquakes are one of the biggest challenges in the design of modern building structures, because seismic forces can cause serious damage if not properly anticipated plus Indonesia's territory is on the Indo-Australian Plate, the Eurasian Plate, and the Pacific Plate. Podium-type buildings are buildings that have problems with the transition of stiffness because there is a relatively large difference in stiffness to relatively small stiffness. One way to anticipate stiffness problems in podium-type buildings is to consider the frame system used because it greatly affects the behavior of podium-type buildings. In this study, the behavior of podium-type buildings using a Special Moment Resisting Frame System is compared with a Dual System using a Shear Wall. The two models were analyzed to see the behavior consisting of basic shear force, interfloor deviation and p-delta influence. From the research obtained, it was concluded that the SMRF building has a basic shear force of 9794.71, 138.53% greater than the Dual System of 2361.96. The maximum inter-floor SMRF inter-floor deviation is 64.405 mm and passes through the permit deviation. For the dual system, the maximum deviation of 29.145 is 54.76% smaller than the SMRF and the influence of p-delta for SMRF and the dual system are still within the safe limit.

Utilization of Rice Husk Ash and Coconut Fibers to Enhance Pervious Concrete in Sustainable Pavement Systems

2025-05-01T14:24:58+07:00

This study examined the influence of rice husk ash and coconut fiber on the mechanical and durability performance of pervious concrete. The concrete mixes were prepared without fine aggregates to maintain high porosity, using a water-to-cement ratio of 0.30 and a coarse aggregate-to-cement ratio of 4.5:1. Rice husk ash replaced 10% or 12% of the cement by weight, while coconut fiber was added at 0.3% and 0.5% by volume. The results showed that both additives slightly reduced porosity and permeability, yet the compressive strength remained above the minimum threshold of 7 MPa. The mix containing 0.3% coconut fiber achieved the highest strength of 11.0 MPa. The most optimal mix combined 10% rice husk ash with 0.5% coconut fiber, producing a porosity of 21%, permeability of 3.8 mm/s, compressive strength of 10 MPa, and water absorption of 250 L/m³. Durability also improved in fiber-containing mixes, as observed from reduced damage under wet-dry cycles. The addition of these natural materials contributed to enhanced mechanical performance and resistance to water-related degradation, making the mix suitable for sustainable pavement systems. Overall, the findings confirmed that rice husk ash and coconut fiber can be effectively utilized as partial replacements in pervious concrete without compromising structural integrity.

Analysis of Structural Damage and Disaster Management Resulting from Earthquakes in Cianjur

2025-07-13T20:13:43+07:00

The earthquake that occurred in the Cianjur area, West Java on Monday 21 November 2022 at 13.21 WIB resulted in 635 fatalities and 56,000 houses that were damaged. Therefore, it is necessary to conduct an assessment and mitigation of the structural damage buildings and the impact of earthquakes. From the results of the assessment carried out in the area where the earthquake occurred, it was found that many houses and public facility buildings still did not meet the requirements for earthquake-resistant buildings, especially in the use of concrete materials, main reinforcement and stirrups in columns, beams, foundations and beam-column joint. The amount of damage to buildings that occurred as a result of the buildings standing did not have a strong column-weak beam planning concept. This can be seen from the inability of the column to withstand/ carry the working load which causes the column to collapse and damage. Therefore, it is very necessary to pay attention to building planning in Disaster Prone Areas (KRB) in accordance with earthquake resistant building regulations SNI 1726:2019 and SNI 2847:2019. In addition, post-disaster management measures should include the assessment of survivors’ health conditions (psychological support and trauma healing), the operational control of healthcare services, the treatment of injured victims and the management of fatalities, the prevention of communicable diseases, the provision of adequate nutrition, the strengthening of information systems and coordination mechanisms, the improvement of sanitation facilities (installation and supply of clean water) and latrines, as well as the deployment of medical personnel and logistics assistance need to be improved and coordinated well after the earthquake.

Evaluation of the Relationship between Water Discharge and Flow Speed on the Volume of Open Channel Sediment in the UKI Campus Area, Jakarta

2025-07-15T22:35:01+07:00

ABSTRACT

Open channels are a common type of channel and require special attention because they often undergo erosion and sedimentation processes. The erosion that occurs in open channels is affected by water discharge as well as flow speed. This study aims to determine the volume of eroded sediment in open channels within the Christian University of Indonesia. The research method uses a simulation approach to obtain an overview of conditions through a small-scale system. Observations were made on a 25-meter-long channel divided into five pias, resulting in six measurement points. The water discharge and flow speed are measured at each point using a current meter. Furthermore, at the sixth point, sediment is added to measure the volume of sediment that has eroded in a certain time span. The observation results show that the flow discharge (Qp) increases as the water level (h) in the channel increases. The larger the discharge that occurs, the greater the volume of sediment erosion that is formed.
