Abstract

ABSTRACTSteel beams are susceptible to initial geometric imperfections due to improper fabrication and installation processes. Consequently, long steel beams without stiffening are prone to bending due to lateral torsion. The purpose of this study is to determine the effect of variations in the initial geometric imperfections of Single Curvature-Moment (SCM) on the moment, total displacement, displacement in the X direction (U1), displacement in the Y direction (U2), and twist. This study used an RH profile with a compact wing and body. The boundary condition used is a simple beam with an initial geometric imperfection due to single moment-curvature (SCM) bending. The variations used are the initial geometric imperfections values of SCM 0 mm (without initial geometric imperfections), SR5 (with initial geometric imperfections of 5 mm), and SR10 (with initial geometric imperfections of 10 mm). Initial geometric imperfections of SCM in steel beam decreased moment capacities up to more than 2% in elastic conditions and 12% in plastic states. This SR10 beam is also a beam that has a displacement of the X-axis (U1 = -203,960 mm), a displacement of the Y-axis (U2 = -255,615 mm), and the most significant twist (28,179 °).Keywords: buckle, initial geometric imperfections, Single Curvature-MomentABSTRAKBalok baja rentan mengalami initial geometric imperfections akibat proses pabrikasi maupun pemasangan yang kurang tepat. Sementara balok baja yang panjang tanpa pengaku rentan mengalami tekuk akibat torsi lateral. Tujuan dari penelitian ini adalah untuk menentukan dampak variasi besarnya initial geometric imperfections Single Curvature-Moment (SCM) terhadap momen, displacement total, displacement arah X (U1), displacement arah Y (U2), dan twist. Penelitian ini menggunakan profil RH dengan sayap dan badan yang kompak. Boundary condition yang digunakan adalah balok sederhana dengan initial geometric imperfections akibat tekuk single momen curvature (SCM). Variasi yang digunakan adalah besarnya nilai initial geometric imperfections SCM 0 mm (tanpa initial geometric imperfections), SR5 (dengan initial geometric imperfections 5 mm), dan SR10 (dengan initial geometric imperfections 10 mm). Dari hasil penelitian diketahui bahwa pada kondisi elastis, leleh, maupun plastis, balok dengan initial geometric imperfections SCM menunjukkan penurunan kapasistas momen mengalami penurunan hingga mencapai lebih dari 2% pada kondisi elastis dan 12% pada kondisi plastis. Balok SR10 juga merupakan balok yang memiliki displacement arah sumbu X (U1=-203,960 mm), displacement arah sumbuY(U2=-255,615 mm), dan twist yang paling paling besar (28,179°).Kata kunci: tekuk, initial geometric imperfections, Single Curvature Moment

Abstract

In the construction planning process, the calculation of the quantity of each project work was packaged in a Bill of Quantity (BoQ) to complete the project and greatly affected the continuity of the entire construction construction process. With advances in technology in the world of construction, it could simplify planning in built a building and could increased the accuracy of calculations without using assumptions that could increased the volume of work. One of the results of current technological advances was the creation of the Building Information Modeling (BIM) method, a method that was able to simulate all information in a development project into a 3-dimensional model. Currently the use of the BIM method in Indonesia was still limited so that in this research, the aim was to determine the effectiveness of the use of BIM on the accuracy calculation of the volume of the BoQ and to know the percentage comparison. The building project that was used as a comparison was a building with the middle rise building category, namely the Central Jakarta BPJS Building. Based on the research conducted, it was found that the difference between conventional and BIM results on pilecap components was 5%, column 6%, beam 35%, floor slabs 2%, stairs 22%, ceiling 2.26% floor coverings 14% lower than conventional calculations but for the wall component the BIM calculation is 0.78% greater than the conventional calculation. So that the total percentage ratio is 10%, thus this proves that the use of the BIM method in calculating quantity was effective in terms of calculation accuracy.

Abstract

Beton porous non pasir dengan slag baja merupakan salah satu beton yang ramah lingkungan. Beton ini dapat menjadi alternatif untuk mengatasi permasalahan kerusakan jalan akibat genangan air, terutama pada trotoar, jalan taman, atau jalan lingkungan dalam skala terbatas. Slag baja dapat menggantikan agregat kasar karena memiliki kuat tekan yang mendekati agregat batu pecah. Penelitian ini bertujuan untuk menganalisis pengaruh substitusi steel slag terhadap kuat tekan beton porous non pasir. Penelitian eksperimental ini menggunakan dua variasi faktor air-semen (w/c 0,25 dan w/c 0,3) dengan dua variasi agregat batu pecah dan steel slag dengan diameter 10 mm-20 mm. Uji tekan pada benda uji dilakukan pada umur 14 hari, 21 hari, dan 28 hari. Penelitian ini mengacu pada ACI 522R 10. Penelitian ini menunjukkan bahwa kuat tekan beton porous non pasir menggunakan steel slag sebagai agregat kasar memiliki kuat tekan yang lebih rendah dibandingkan beton tidak halus porous menggunakan batu pecah.

Abstract

Rumah Sakit Umum Daerah (RSUD) Kota Depok merupakan rumah sakit yang dibangun oleh pemerintah Kota Depok. Gedung F RSUD Kota Depok pada tahun 2013 silam pernah dibangun tetapi proses pembangunan ini terhenti sejak triwulan 2014. Kondisi elemen struktur atas yang ada (kolom lantai) yang sudah terbangun tidak terawat sehingga terjadi penurunan mutu beton. Pengujian hammer test menunjukkan mutu beton pada kolom tersebut sebesar 20,59 MPa yang kurang dari kekuatan rencana Fc’ 25 MPa. Perencanaan lama (pada tahun 2013) berdasarkan peraturan SNI 1727-2013 dan SNI 1726-2012. Padahal saat ini sudah ada peraturan terbaru yaitu SNI 1727-2020 dan SNI 1726-2019. Metode penelitian yang digunakan dalam penelitian ini adalah metode permodelan dan analisis struktur menggunakan software bantu Tekla Structural Designer (TSD). Ada dua model yang digunakan dalam penelitian ini yaitu Model A dan Model B. Model A menggunakan dimensi sesuai dengan DED dan Model B menggunakan hasil redesain. Kedua model ini memiliki perencanaan pembebanan, tumpuan mutu beton dan mutu tulangan yang sama. Namun memiliki perbedaan dalam dimensi penampang balok kolom pelat  serta jumlah dan tulangan yang digunakan. Adapun tujuan dari penelitian ini adalah untuk menganalisis peningkatkan desain kapasitas struktur atas beton bertulang Gedung F RSUD Depok. Pada abstrak ini akan disebutkan peningkatan desain kapasitas terbesar, untuk pelat beton mengalami peningkatan sebesar P1 8,35 kNm, P2 13,22 kNm Sementara itu, desain kapasitas balok meningkat sekitar GB1 187,543 kNm, GB3 85,17 kNm, B1 84,02 kNm dan desain kapasistas kolom meningkat sebesar K1 322,95 kNm, K2 487,36 kNm, K3 420,32 kNm dari kapasitas awalnya (Model A). Oleh karena itu, adanya peningkatan dimensi penampang balok kolom pelat serta jumlah dan tulangan, dapat meningkatan desain kapasitas struktur atas beton bertulang.Rumah Sakit Umum Daerah (RSUD) Kota Depok merupakan rumah sakit yang dibangun oleh pemerintah Kota Depok.

Abstract

Abstract Problems related to road damage are currently growing. Damages that occur are often caused by waterlogging. One of the efforts that can be done is by applying the use of porous concrete. Porous concrete can reduce water runoff and increase infiltration in the soil because it has a high porosity. As a substitute material, steel slag can be an alternative in replacing coarse aggregate. Steel slag is an abundant waste from steel production industrial companies. Currently, steel slag is widely used in high-strength concrete mixes. This study of porous concrete generally refers to ACI 522R 10. The purpose of this study was to analyze the effect of steel slag substitution on the tensile strength and permeability of porous concrete. This experimental study used two variations of the w/c (0.25 and 0.30) with two variations of crushed stone aggregate and steel slag with a diameter of 10 mm-20 mm. The tensile strength and permeability specimen of porous concrete is in the form of a concrete cylinder (15 cm diameter, 30 cm height) with 3 samples of each variation. The tests were carried out at the age of 28 days. Based on the experimental results on porous concrete with steel slag or crushed stone, the value of the tensile strength of concrete with w/c 0.30 is higher than w/c 0.25. Meanwhile, the permeability value of porous concrete in both the mixed variant of steel slag and crushed stone with w/c 0.25 is higher than w/c 0.30. So that the relationship of the tensile strength of concrete is inversely proportional to the value of the permeability of the concrete in the conditions of the two w/c (0.25 and 0.30).

Abstract

AbstractKeramasan Bridge 2 is a bridge with an age of more than 30 years, so it is necessary to review its feasibility and serviceability. Based on the loading test results, it is stated that the deflection on the girder exceeds the permissible deflection. Based on this, it is necessary to strengthen the upper structure. The strengthening of the upper structure is carried out by installing a diaphragm between the girders. The diaphragm is an angled steel profile of 100 mm x 100 mm with a thickness of 10 mm.To determine the number and position of diaphragms, two alternatives were analyzed. The first alternative is to add three diaphragms at 1/4, 1/2, and 3/4 span. In the first alternative, the deflection value is 26.9754 mm. In the second alternative, the diaphragm is installed every 3 meters distance. The addition of the diaphragm produces a deflection of 27.1634 mm. The results of the analysis indicate that with the addition of a diaphragm, there is a reduction in deflection. In the first and second alternatives, a deflection that meets the permissible deflection is produced (31.375 mm). Considering the safety factor, the first alternative is used because adding three diaphragms affords the smallest deflection (26.9754 mm).Keywords: Deflections, Diaphragm, Strength, Bridge Upper Structure
