Journal of Civil Engineering (eISSN 2579-9029/pISSN 2086-1206) is a new journal that preceded by the previous Civil Engineering Department ITS Journal which was well known as Jurnal Teknologi dan Rekayasa Sipil (TORSI). TORSI journal was established in March 1981. In 2009, TORSI journal name was changed to Journal of Civil Engineering. Journal of Civil Engineering is managed by Pusat Publikasi Ilmiah LPPM Institut Teknologi Sepuluh Nopember (ITS). Journal of Civil Engineering published at least five papers for each volume. Annually two volumes are published with the first volume is published within the period of January-June and the second volume is published within the period of July-December. The Peer-review process is online based using the OJS portal. Focus and Scope The Journal of Civil Engineering (JCE) publish scientific article which is specific for civil engineering. JCE article must be written either in Indonesian or English languages. The focus and scope of the journal are: 1. Structures (High-Rise Building, Bridges, Long-Span Bridges) 2. Materials (Concrete, Steel, Fiber-Reinforced Concrete, Composites) 3. Hydraulics and Hydrology 4. Geotechnics (Foundation, Embankment Stability) 5. Construction Management 6. Transportations (Highways, Trains, etc.) 7. Green Buildings and Architectures

Abstract

This study presents a series of finite element analyses on the prototype of masonry house retrofitted using FRP strips.The model of the masonry house refers to the prototype scaled to 1:3 tested in an experimental campaign. The non-linear behaviorof masonry is modeled through the Concrete Damage Plasticity (CDP) model, while the FRP and adhesive are modeled as twoseparated isotropic solid materials with elastic-plastic behavior. A good agreement between experimental and numerical resultis obtained, indicating the increase of bearing capacity of the reinforced masonry prototype.

Abstract

Resource allocation commonly becomes one of the critical problems in project scheduling. This issue usually occursbecause project managers estimate the schedule of activities and network time without considering resource availability.Resource-Constrained Project Scheduling Problem (RCPSP) links to the allocation of resources or set of resources into certainactivities in order to accomplish particular objectives. Various approaches have been performed to overcome RCPSP, includingthe heuristic approach. In this research, Ant Colony Algorithm is used to solve RCPSP. There are 11 examples of projects beinginvestigated with dissimilarity in-network and several activities. The implementation of the Ant Colony Algorithm resulted inthe percentage of a near-optimal solution of 63.64%. Besides, the duration obtained from the algorithm above the manualscheduling (assumed optimal) was only 4.29%. Sensitivity analysis was performed to understand how substantially the changesof ACO parameters influenced the result obtained from the algorithm. Based on the result, it could be concluded that theparameters of ACO have no significant effect to project duration.

Abstract

Strut and tie model (STM) is more suitable to design the pierhead structures which resist high shear forces transferredfrom the girders. These pierhead structures behave like the disturbed regions as in reinforced concrete deep beam. The designof the struts and ties elements requires the initial geometry configuration of the truss model where its boundaries are limited bythe shape of the pier head structures. To find the optimum topological shape of the truss model, the genetic algorithm (GA)optimization technique is used in this paper. The objective functions in the GA optimization consisted of minimizing the usageof concrete and steel reinforcement material and ensuring all the stress ratios of the strut and tie elements are less than equalto unity. Both prestressed and non-prestressed pierheads are investigated in this paper. The use of prestressing in the pierheadstructures reduces the stresses in the main tension tie significantly. Some shear tie and compression struts members also havealmost zero stresses due to the presence of prestressing forces. For these elements with zero stresses, the elements can beremoved and reduces the concrete and rebar materials usage. Furthermore, the genetic algorithm optimization is found to besuccessful to ensure all the stress ratio in the members to be less than equal to unity.

Abstract

A spectral wave numerical simulation based on SWAN is used to model 10 years wave climate at Rote Strait, NusaTenggara Timur province. ERA5 reanalysis data of total wave and wind is used for model forcing. Simulation results showwaves direction in Rote strait are coming from southeast and southwest. Waves direction at nearshore of southeast Timor islandcoast are coming from southeast because of refraction and diffraction. Waves height over 0.8 m occurs in 320 days in one year.50 years wave return period calculated at 2.68 m height. Indeed, port development in Rote strait area need to consider the downtime caused by waves and extreme wave forces in the design.
