Abstract

3D Concrete Printing (3DCP) provides many advantages for construction industry especially on productivity, waste, labor, and environment. Many researches have been conducted on the material development for 3DCP. However, there are not many researches which study the structural behavior of 3DCP. This experimental research aims to analyze flexural and shear behavior of 3D printed reinforced concrete beams. Five longitudinal reinforcement ratios were used to analyze crack patterns, failure mode, ductility, and capacity of those beams. The experimental results were then compared with analytical results by using ACI design code. The results show that higher longitudinal reinforcement ratio yields higher flexural and shear capacity of 3DCP beams. Due to layer-by-layer printing process, 3DCP beams are prone to local failure of filaments. Placement of longitudinal reinforcement might initiate macroscopic voids which could cause slippage and sudden drop on the capacity. Furthermore, ACI code underestimates the capacity of 3DCP beams failing in shear by some margins.

Abstract

This study is aimed to compare the seismic performance of simply supported hollow slab on pile group (SHSPG) structures designed as “critical” and “essential” viaducts with shear panel damper (SPD) devices. There were three numerical models to be compared, namely SHSPG-A, SHSPG-B, and SHSPG-C. SHSPG-A is a “critical” viaduct with 35 piles per one pile head. SHSPG-B is an “essential” viaduct with 18 piles per one pile head. SHSPG-C is an “essential” viaduct with 18 piles per one pile head plus sixteen SPDs. Numerical models considered the prestressing effect of the spun pile. Nonlinear time history analyses were executed using seven pairs of recorded ground motions that had been scaled and adjusted to the seismic characteristics of Yogyakarta, Indonesia. As the result, the performance level of SHSPG-A was much better than SHSPG-B. The SPDs application could maintain SHSPG-C’s performance at the same level as SHSPG-A and dissipate 34.28%-53.03% of the seismic energy.

Abstract

This study considers the problem of finding weights for building characteristics and compares buildings in property valuation to provide a more rigorous analytical foundation for a simple yet practical valuation technique knowns as Quality Rating Valuation Estimation (QRVE). Mathematically, we prove that the “best” characteristic weights can be obtained from Multiple Linear Regression Analysis (MRA) coefficients. Furthermore, by applying the Gower Similarity index and the Partition Around Medoid (PAM) clustering technique, the proposed algorithm provides an appropriate similarity of the weighing of compared buildings. The case studies illustrate a way to select a subset of characteristics when there are many of them with two numerical examples, as well as a complete modification of QRVE in conjunction with the grid adjustment technique. The modified QRVE proposal results in a very reasonable and high valuation performance of the building value estimate.

Abstract

In a typical building design, the interaction between building and surrounding soils is often ignored. Since soil is deformable and has limited capacity to resist loads, this interaction, called soil-structure interaction (SSI), could alter building responses, especially during earthquake loadings for buildings with significant basement depths. In this study, a 10-story reinforced concrete building with 3-level basement was used to evaluate the effects of SSI on building during earthquakes. Dynamic time response analyses were performed using earthquake time histories scaled to a design response spectrum for a Surabaya, Indonesia, location. Soil responses during earthquakes were modeled using nonlinear hysteresis normal and elastic-perfectly plastic frictional soil springs, developed using the hardening soil with small strain stiffness model. Depth-varying ground motions were also applied along the basement depth. The results show inconclusive SSI effects, where some of the time histories produce greater base shears and inter-story drifts when SSI is considered, while others show the opposite results.

Abstract

The parts of Yogyakarta-Bawen Toll Road Indonesia, based on the geological agency’s liquefaction susceptibility map are located on moderately susceptible to liquefaction soil. This map can be a preliminary indication of liquefaction as it can roughly indicate liquefaction potential. However, it cannot illustrate the actual condition in detail as its inputs are macro parameters (geological and seismicity factors). The existence of silty sand and sand, earthquake sources, and shallow groundwater increase the liquefaction possibility to occur in this important national project. Therefore, the Liquefaction Severity Index (LSI) and the Liquefaction Potential Index (LPI) using Sonmez’s and Iwasaki’s analysis methods are conducted with peak ground acceleration (PGA) of 0.322 g for the first section and in the second section 0.298 g. The results of the three types of analysis have relatively similar trends but the differences are in each category. The LSI’s categories are very low-moderate in the observed location, meanwhile, the LPI’s categories are low-very high.

Abstract

This study examines issues related to the Trans Mamminasata Bus/Teman Bus, Indonesia, particularly in Corridors 2 and 3. Using primary and secondary data obtained from a survey, this study explores the service coverage area for three facilities (housing facilities, government and educational infrastructures) along the Corridors 2 and 3 using network analysis in Quantum GIS (QGIS). Two variables, pedestrian distance (400 meters) and cyclist distance (2000 meters), were applied in this study. The results showed that Corridor 2 served 86 infrastructures for the pedestrian distance variable and 367 infrastructures for the cyclist distance variable, while Corridor 3 served 89 infrastructures for the pedestrian distance variable and 217 infrastructures for the cyclist distance variable. The study found that the total service coverage area along Corridors 2 and 3 is wider for cyclists than for pedestrians. Moreover, this study highlights the presence of urban sprawl in the regions served by both Corridors.

Abstract

Indonesia, an archipelago with vast coastal areas consisting of 809 coastal villages, still faces the same problems of clean water scarcity and accessibility. This research goals are to discover appropriate inexpensive local filtering media and lower the salinity of brackish water in Sidoarjo Regency Indonesia. Regarding previous invention and research, this study deploy an experimental method by physical experiment including local materials along with  chemical experiment: ion exchangers as well as reverse osmosis (RO). The outcomes demonstrate that local media filtration utilizing a combination of a 10-micron filter, kaolin, zeolite, kaolin, activated carbon, and kaolin is the best combination to produce the most transparent, and odorless water. It can reduce Total Dissolved Solid (TDS) and Electrical Conductivity (EC) values by 8.59% and 7.18%, and reduce pH levels by 2.59%. On the other hand, reverse osmosis and ion exchange can achieve 99.5% and 67% reductions in TDS and EC values, respectively.
