Abstract

Waterproofing plays a crucial role in maintaining a building's integrity. However, subcontractor skill limitations and project constraints such as design changes, site readiness, and resource shortages often cause delays. This study analyses the planning and time control of waterproofing work in the Building X High-Rise Data Center project, covering eight work items. Using the Precedence Diagram Method (PDM), the work schedule indicates an effective duration of 34 weeks. The analysis methods used include Critical Path Method (CPM), Earned Value Analysis (EVA), Program Evaluation Review Technique (PERT), and crashing for project duration optimization. By the 30th week, the calculation results showed a Schedule Performance Index (SPI) of 0.96 and a Schedule Variance (SV) of -Rp120,057,209.0, indicating project schedule delays. In terms of cost, the Cost Performance Index (CPI) was 0.99, and the Cost Variance (CV) was -Rp26,459,888.0, showing cost overruns, though still within a relatively controlled limit. The probability of project completion reached 90% by the 30th week. Optimization through acceleration methods proved effective in reducing project duration with controlled additional costs. Therefore, better mitigation strategies are needed to minimize time and cost deviations in similar future projects.

Abstract

This paper describes the findings of a research study aimed at evaluating the impact of various parameters on the stress-strain behavior of concrete composed of artificial lightweight aggregates with rectangular cross-sections. The factors that were evaluated include the number of fiber-reinforced polymer (FRP) layers, the compressive strength of the concrete, and the cross-sectional shape of the concrete. A total of twenty-two test specimens were fabricated, wrapped with Fiber Reinforced Polymer (FRP), and subjected to concentric compressive loading for experimental evaluation. The experimental findings indicate that Fiber Reinforced Polymer (FRP) demonstrates an excellent wrapping technique for lightweight concrete composed of lightweight aggregate. In addition to this, the test findings indicate a positive correlation between the number of fiber-reinforced polymer (FRP) layers employed and the resultant ultimate stress and strain shown by concrete composed of artificial lightweight aggregate. The test results additionally demonstrate a clear relationship between the rise in ultimate stress and the compressive strength of concrete, while showing an inverse relationship with the ultimate strain observed. Similarly, the test results indicate that the utilization of Fiber Reinforced Polymer (FRP) wrapping has more efficacy when applied to round cross-sectional shapes as opposed to rectangular cross-sectional shapes.

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

Studi desain berbasis kinerja seismik dengan menggunakan pendekatan Direct-Displace­ment Based Design (DBD) metode Single-Degree-of-Freedom (SDOF) equivalent system yang berdasarkan ragam getar pertamanya, telah banyak dilakukan di Indonesia, namun studi pengujian DBD metode Multiple-Degree-of-Freedom (MDOF) equivalent system yang dapat menangkap pengaruh empat ragam getar, masih minim dilakukan. Penelitian ini melakukan pengujian desain berbasis kinerja seismik menggunakan pendekatan DBD metode MDOF equivalent system dengan tiga buah subjek studi berupa struktur rangka baja terbreis eksentris tiga dimensi, dan sebagai verifikasinya menggunakan analisis non­linear modal time history. Hasil uji menunjukkan bila DBD metode MDOF equivalent sys­tem memberikan akurasi yang kurang baik, juga pada studi ini menunjukkan analisis non­linear modal time history memberikan efisiensi waktu yang sangat baik dengan rata-rata galat yang masih dapat diterima.

Abstract

Precast concrete offers several advantages compared to conventional systems; precast concrete structure technology has become a strategy to enhance standardization, quality control, labor efficiency, and reduce environmental impact and construction pollution. The U-Shell precast beam is a reinforced concrete beam with a 'U' shape designed to enhance practicality and expedite the construction process as it does not require additional formwork and shoring during implementation. The U-Shell beam functions as a permanent formwork, and its design follows either monolithic or conventional methods. In multi-story buildings, using U-Shell beam can increase practical value, reduce costs, and improve time efficiency because they do not require additional formwork and scaffolding in the implementation application. This research involves the development of U-Shell precast beams, structure loading considering various loads, modeling using computer program to determine the structural reactions on each element, reinforcement design for the U-Shell beam structure, and analysis of the lifting and assembly of U-Shell precast beam. The building selected for reviewing U-Shell beams is the Building with a Special Moment Resisting Frame System. From the results of the analysis, the researcher drew several conclusions regarding the reinforcement design for the U-Shell beam under both conditions. In the condition before composite, the number of installed main reinforcements is 6 with a diameter of 13 mm, while in the condition after composite, the number increases to 8 with a diameter of 16 mm. Lifting reinforcement requires a diameter of 10 mm. The difference in reinforcement between before composite and after composite conditions is because before the composite the beam is still receiving self-load, whereas for the after composite condition the change in moment occurs. After all, the beam has received self-load and other loads. The development and analysis of an innovative precast concrete U-Sheel beam has complied with strength and serviceability.

Abstract

The use of stiffening elements in steel plate shear wall (SPSW) systems enhances lateral stiffness and energy dissipation capacity; however, it also significantly increases material and labor costs due to the complexity of fabrication and installation. As an alternative, the Corrugated Steel Plate Shear Wall (CoSPSW) system has been proposed as a more efficient and practical solution that maintains sufficient stiffness and strength without requiring additional stiffeners. This study investigates the structural performance of CoSPSWs with varying corrugation geometries using the finite element method. The analysis focuses on the influence of the corrugation angle on the overall structural behavior, including buckling stability, lateral stiffness, ultimate strength, and energy dissipation capacity. Nonlinear finite element simulations were conducted using ABAQUS software to capture the influence of geometric nonlinearities under lateral cyclic loading. The results show that increasing the corrugation angle significantly improves lateral stiffness and energy dissipation capacity, while maintaining stable post-buckling behavior. An optimal corrugation angle of approximately 60° provides the maximum strength and ductility among the specimens. This study contributes to understanding the behavior of corrugated steel shear walls and provides valuable insights for the design of efficient, cost-effective steel structures.

Abstract

The warehouse frame is a specialized steel structure requiring more complexcalculations than standard portal frames. This study investigates the impact ofrafter angle and span length on ductility and stability. Results indicate thatincreasing span length enhances ductility but reduces stability due to higher storydrift. For example, M1 (10-meter span) shows a ductility of 4.62 and story drift of13.64 mm, while M3 (20-meter span) achieves 5.07 (+9.62%) with a drift of 46.77mm. A larger rafter angle slightly increases ductility but decreases stability. M1 (10°angle) records 4.62 ductility and 13.64 mm drift, whereas M7 (20° angle) reaches4.71 (+1.79%) with 16.92 mm drift. Higher structure stiffness reduces ductility butboosts stability. M3 (128.29 kN/m stiffness) shows 5.07 ductility and 46.77 mmdrift, while M12 (192.67 kN/m) records 4.96 (-2.17%) with 29.68 mm drift. DespiteM12's minor ductility reduction, M3 demonstrates better elastic-plastic behavior.These findings reveal a clear polarity between ductility and stability.

Abstract

In half-through bridge or pony steel bridge, that is a bridge without upper windbracing, strength of the bridge is determined mainly by the lateral bucklingstrength of its upper chord. Buckling strength of this chord is provided by theflexural stiffness of vertical web member, cross beam, and diagonal beam. In orderto improve the stiffness of vertical web member, triangular steel profile that wasquite high was added to the inner side of bridge for reducing the clearance widthin bridge and disturbing traffic or pedestrian. In this research, stiffness of thevertical web member was improved by using the non-prismatic cross section andadding the triangular stiffener as high as the concrete deck. Finite ElementAnalysis for the lateral stiffness of bridge cross section used a 3D element modelwhich has been validated by previous study. This numerical study was conductedto validate the Engesser theory for determining the lateral elastic stiffness fromupper chord. Study shows the result that accuracy of 3D element model isextremely high, compared with analytic method. Lateral elastic stiffness of bridgein general increased along with the stiffness of vertical web member. However, itcan be concluded that effect on the capability of lateral buckling in upper chordwas not too significant, as a consequence of the increase in stiffness of verticalweb member. Critical lateral buckling occurred in an inelastic range, in which thecritical inelastic buckling stress was determined using small tangent modulus asalternative of modulus of elasticity.
