When it rains, the quantity of river water exceeds its capacity or becomes too much, and there will be inundation caused by overflowing rivers. Factors of natural events such as high rainfall intensity cause flooding, coupled with factors from human activities. This study aims to investigate flood characteristics by developing an integrated model between hydrology and hydraulics. The development of this flood model is based on the hydrological model of runoff using the synthetic unit hydrograph method Soil Conservation Service (SCS), a one-dimensional (1D) hydraulic model for water flow propagation in macro drainage systems, and two dimensions (2D) for calculations if the river flow exceeds the existing capacity so that it experiences water propagation in the inundation area using the HEC-RAS software. To model the flood inundation it is required data Digital Elevation Model (DEM) was obtained by measuring the height of the land using a Total Station (TS) measuring instrument and analyzed using ArcMap software. The calculation of direct runoff is designed for a 5-year return period. The simulation results indicate that the Baturaja Permai area is an area that is prone to flooding with inundation depth of 0.558 m - 4.692 m and a peak runoff discharge of 15.6 m³/s at a 5-year return period.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122189041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Better concrete quality and precision are two advantages that can make precast technology a solution in accelerating bridge construction. Commonly, segmental precast concrete piers are not designed to resist earthquake loads; however, the use of segmental piers systems is still possible in seismic zones by limiting additional dead loads. This study discusses the load limitation using the dynamic response calculation methodology of segmental precast concrete pillar structures to the El Centro (1940) earthquake load by varying the slenderness of the piers/column between 22 to 100. Examination of the stress combination due to axial load (DL) and inertia load due to the earthquake is carried out to find out how much residual stress can be accommodated by the piers/columns. Additional dead load (WADD) is obtained by using Newton's second law by dividing the allowable additional inertial load based on the residual stress to the peak ground acceleration. The calculation results show a good correlation between piers’/columns’ slenderness and the proportion of additional dead load (WADD) to dead load (WDL), so that the applicability of using segmental precast concrete piers/columns in seismic zones can be predicted earlier through this correlation.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124331545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equation consists of a series of hyperbolic tangent functions, with the number of series being the same as the number on the node in the hidden layer. The ANN model consists of 3 layers: the input layer consists of four nodes, the hidden layer has seven nodes and one node in the output layer. The input parameters used are parameters related to distance, discharge, roughness, and depth of flow at the downstream end of the channel. The output parameter is the flow depth at various points. The model has been used to estimate the water level profile for different flow conditions. The comparison between the explicit ANN model and the numerical model results is satisfactory. The models can be extended to study more complex flows and non-prismatic channels. The model is promising as a tool in decision support.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126628503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different locations have different subgrade conditions. Different soil characteristics in different locations call for different treatment or stabilization measures. Poor subgrade strength is observed in Pronoyudo Street in Junrejo Sub-District, Batu City. This is evidenced by the cracked and chipped asphalt surface. The method used to determine the type and level of road damage in the study was Road Condition Index (RCI), while subgrade strength or CBR (California Bearing Ratio) was determined using DCP. In addition, sieve analysis was also performed for foundation material as well as testing water content and subgrade plasticity. Observations were made along 1,000 m (1 km) which was divided into 200 sq m. The analysis results showed a mean Road Condition Index (RCI) of 6.96% and the mean CBR value using the DCP tool was 2.48% (< 5%) with a DDT value of 3.39.

A review related to several studies that have been carried out previously on the properties of ECC and their constituent materials is presented in this paper. The behavior of the material is reviewed as an investigation parameter followed by determining the composition of the mixture, namely the effect of the water-cement ratio, the shape and length of the fiber and the addition of additives. The fiber volume fraction review was limited to between 2% to 3%, which resulted in outstanding tensile strain behavior. As it is known, ECC has an excellent capacity in terms of strain behavior which is accompanied by a large number of mico cracking patterns. ECC crack widths are usually predominantly less than 100 μm. ECC behavior is closer to that of steel which can bend or be ductile, whereas conventional concrete is brittle.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115943347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
