Abstract

Cement-treated base (CTB) is a type of foundation material commonly used in pavement structures which initially has high stiffness, but due to repeated loads CTB tends to experience more cracks which can cause a decrease in its elastic modulus. This study aims to determine the extent of damage and decrease in the value of CTB's elastic modulus before and after cracking through ultrasonic pulse velocity (UPV) test and unconfined compressive strength (UCS) tests on CTB cylinder samples. The CTB material quality index was evaluated using a concrete quality designation (CQD). The results showed that the magnitude of stress applied to  CTB affects the degree of damage, and the degree of damage to CTB significantly affects the material’s modulus of elasticity. The greater the degree of damage to CTB, the smaller the elastic modulus will be. For applied stress with CTB damage level of 32%, the elastic modulus decreases by 33.55%. The level of damage caused by the application of the maximum stress (100%) on CTB sample reached 95.29%, and the modulus of elasticity decreased by 83.30%. The CTB sample with 95.29% degree of damage has the same elastic modulus as the unbound granular aggregate material.

Abstract

Estimating construction project costs is usually done manually; it takes a long time, and the more comprehensive the estimate, the more manual calculations must be performed, increasing the risk of human errors. This study aims to make a building cost estimation application using the 2022 Work Unit Price Analysis (AHSP), based on excel macros, so that cost estimates become more accurate and efficient. The first step is to design the framework and application design and then analyze the database requirements. The second step: database creation and application interface design. The third step: testing, validation, and verification on two building projects in 2022. The estimation results of this application are very accurate and efficient, where the total cost is Rp. 382,998,432.00, while the bid price is Rp. 383,000,000.00. There is a difference in calculation costs compared to the bid price, which is Rp. 1,568.00 (0.00041%).

Abstract

Project performance is an essential reference in supporting the success of construction implementation so that costs and completion time are according to plan. Previous research states that projects that experience delays will impact cost overruns which can be detrimental to contractors and project owners. This study takes the case of a performance evaluation on a building construction project that experienced a delay of 15.496% (25th week). The performance measurement results using the earned value, the project has an SPI value = 0.493, meaning that the project experienced significant delays. If the project is not controlled, it will take 72 weeks to complete from the 48-week plan at the cost of Rp. 64.57 billion from Rp. 57.23 billion. Control of this project needs acceleration which was carried out using the Crash Program method in 2 ways: (i) increasing the number of workers and (ii) maintaining the number of existing workers but increasing overtime hours. A practical solution alternative is to increase the number of workers, which results in a project completion time of 43 weeks with a final project cost of IDR 58.89 billion

Abstract

Concrete Filled Double Skin Steel Tubes (CFDSTs) merupakan struktur komposit yang memanfaatkan penampang baja ganda yang diisi beton. CFDSTs banyak digunakan dalam konstruksi bangunan modern karena memiliki kinerja struktural yang baik dikarenakan bagian berongga penampang baja berfungsi sebagai tulangan dan bekisting untuk beton, sedangkan beton sendiri berfungsi untuk menghilangkan atau menunda tekuk lokal pada bagian berongga penampang baja serta meningkatkan daktilitas penampang secara signifikan. CFDST sendiri mempunyai keuntungan dibandingkan dengan struktur komposit tabung baja yang terisi penuh beton yaitu peningkatan modulus penampang, peningkatan stabilitas, bobot yang lebih ringan, karakteristik redaman yang lebih baik dan kinerja siklik yang lebih baik. Penelitian ini menganalisis struktur komposit CFDSTs tipe Circular Hollow Section (CHS) dan Square Hollow Section (SHS) dengan beberapa variasi. Proses analisis dilakukan dengan melakukan permodelan dengan finite element method menggunakan software Abaqus CAE dengan serangkaian test siklik pada struktur kolom. Hasil analisis yang di peroleh menunjukan bahwa model SHS lebih unggul dari pada model CHS dalam segi nilai kapasitas geser, mendisipasi energi dan kemampuan daktilitasnya

Abstract

Liquefaction is the condition of the soil that loses shear strength due to an earthquake, so the capacity of the soil decreases suddenly. Liquefaction occurs in water-saturated sand soils, such as in breakwater of South Bali coast with the magnitude earthquake of 6.8 based on BMKG data in 2011. This condition allows liquefaction to occur under the breakwater. This study aims to identify the potential and thickness of the liquefaction layer based on the N-SPT value at 4 bore hole using 3 methods, namely the Seed-Idriss method, the NCEER method, and the Tokimatsu-Yoshimi method, and design ground improvement with vibro compaction to overcome liquefaction problems. Based on the results of 3 methods analysis, the potential for liquefaction occurred in all bore hole zones with a thickness of 5 to 9 m from the ground surface. The ground improvement design uses vibro compaction with a triangular pattern, spacing 2.1 m. Ground improvement increases the liquefaction FS value, so the potential for liquefaction in all bore hole zones does not occur

Abstract

Natural frequency is one of the factors in bridge construction. Because the natural frequency can be used as an indicator to detect the ability of the bridge, including the ability to withstand resonance. In addition, the natural frequency is also a way to analyze damage that will or has already occurred to a bridge. One of the analytical methods that can be used to analyze natural frequency values is the Undamped-Degree of Freedom. The results of this study indicate that the natural frequency value of the Sei Wampu Bridge has a value of 10.97 rad/s for the first mode, 18.06 rad/sec for the second ,mode and 20.34 rad/sec for the third mode. From the results of this analysis, it can be seen that the natural frequency value will increase as the bridge mode increases.

Abstract

Compaction is essential in achieving the desired density of fill materials in accordance with technical specifications. There are existing differences in the compaction methods employed in the field and at laboratory testing, with in field using rolling compaction, while the laboratory employs pounding compaction. The objective of this study is to compare static and dynamic laboratory compaction methods and their effects on shear strength. Shear strength testing is conducted using the Triaxial Unconsolidated Undrained (TX-UU) approach. The research findings show that in laboratory compaction of low plasticity silt (ML) samples, there is a dry unit weight difference of 2.90%, and for high plasticity silt (MH) samples, a dry unit weight difference of 3.42% is observed when switching from dynamic compaction to static compaction. Additionally, the shear strength values for ML and MH samples increase by 10.37% and 13.63%, respectively, when switching from dynamic to static compaction. These results demonstrate that compaction energy and shear strength are positively correlated.
