Abstract

This paper presents Multi-Objective Integer Non-Linear Programming (MOINLP) involving Negative Total Float (NTF) for improving the basic model of Multi-Objective Programming (MOP) in case the optimization of the additional cost for Project Scheduling Compression (PSC). Using the basic MOP to solve the more complex problems is a challenging task. We suspect that Negative Total Float (NTF) having an indication to make the basic MOP to solve the more general case, both simple and complex of PSC. The purpose of this research is identifying the conflicting objectives in PSC problem using NTF and improving MOINLP by involving the NTF parameter to solve the PSC problem. The Solver Application, which is an add-in of MS Excel, is used to perform optimization process to the model developed. The results show that NTF has an important role to identify the conflicting objectives in PSC. We define NTF is an automatic maximum value of the activity duration reduction to achieve due date of PSC. Furthermore, the use of NTF as a constraint in MOINLP can solve the more general case for both simple and complex PSC problem. Base on the condition, we state that the basic MOP is still significant to solve the PSC complex problems using MOINLP as a sophisticated MOP technique.

Abstract: Concrete as a building material has become the main choice in any building construction. Generally the craking by damage of structural components repaired by epoxy injection. This research was conducted to observe shear behavior analysis of high strength reinforced concrete beams after crack that repaired by epoxy injection system. In this research had 4 beams tested with measuring (15 x 30 x 220) cm for each epoxy age variation has a beam specimen which was 7 days (BBMTG E-7), 14 days (BBMTG E-14), 28 days (BBMTG E-28) and a beam specimen will be tested normally as comparison. Specimens were designed to have shear failure. Tensile reinforcement has 18,9 mm diameter as many as 4 pieces, tension reinforcement has 15,8 mm diameter as many as 2 pieces and shear reinforcement has 6 mm diameter with interval of 300 mm. High Strength Concrete obtained about 66,62MPa with W/C Ratio 0,25. The results showed that all beams had shear failure as planned. The result showed that repairing age concrete by epoxy injection system influence the shear of high strength concrete capacity. It is showed by the maximum load reached by BBMTG E-7 about 20,81 T and BBMTG E-14 about 19,6 T didn?t reach a maximum load of BBMTG Normal about 26,03 T, moreover of BBMTG E-14 maximum load value is shorter than BBMTG E-7 maximum load value. Maximum load by BBMTG E-28 about 25,55 T  which is close to BBMTG Normal maximum load value. Crack repaired do not reopen after retesting, instead new nearby the initial crack. Repair of high strength concrete by using epoxy injection system could be add a brittleness of high reinforce concrete. This would be caused by epoxy resin material which had the same quality with high strength concrete.Abstrak: Beton sebagai bahan bangunan telah menjadi pilihan utama dalam setiap pekerjaan konstruksi bangunan. Umumnya retak akibat kerusakan pada komponen struktur diperbaiki dengan injeksi epoxy. Penelitian ini dilakukan dengan tujuan untuk mengamati perilaku geser pada balok beton bertulang mutu tinggi yang telah diperbaiki dengan sistem injeksi epoxy. Pada penelitian  ini diuji 4 buah balok berukuran (15 x 30 x 220) cm untuk masing-masing variasi umur epoxy sebanyak satu benda uji balok yaitu berumur 7 hari (BBMTG E-7), 14 hari (BBMTG E-14), 28 hari (BBMTG E-28) dan satu benda uji balok yang akan diuji secara normal sebagai pembanding. Benda uji didesain untuk mengalami gagal geser. Tulangan yang digunakan adalah besi ulir diameter 18,9 mm sebanyak 4 buah sebagai tulangan tarik dan besi ulir diameter 15,8 mm sebanyak 2 buah sebagai tulangan tekan. Sedangkan untuk tulangan geser digunakan besi polos diameter 6 mm dengan jarak 300 mm. Kuat tekan Beton Mutu Tinggi Geser yang diperoleh sebesar 66,62 MPa dengan FAS 0,25. Hasil penelitian menunjukan bahwa semua balok mengalami gagal geser sesuai yang direncanakan. Hasil penelitian meunjukkan umur perbaikan beton dengan sistem injeksi epoxy berpengaruh terhadap kapasitas geser beton mutu tinggi. Hal ini ditunjukkan dengan beban maksimum yang dicapai BBMTG E-7 sebesar 20,81 T dan BBMTG E-14 sebesar 19,60 T tidak mencapai nilai beban maksimum BBMTG Normal sebesar 26,03 T, bahkan nilai beban maksimum BBMTG E-14 lebih rendah daripada nilai beban maksimum BBMTG E-7. Nilai beban maksimum BBMTG E-28 sebesar 25,52 T yang paling mendekati dengan nilai beban maksimum BBMTG Normal. Retak yang diperbaiki tidak terbuka kembali setelah pengujian ulang, sebaliknya muncul retak baru disekitar retak yang lama. Perbaikan beton mutu tinggi dengan menggunakan sistem injeksi epoxy menambah sifat kegetasan beton mutu tinggi. Hal ini disebabkan karena material epoxy resin memiliki kekuatan yang hampir sama dengan beton mutu tinggi.

Abstract: High Strength Concrete is an alternative construction material for supporting heavy loads. High strength concrete is a brittle material that susceptible to crack. One of the concrete repairing method is epoxy injection. The aim of this study is to determine the flexural behavior of high strength reinforced concrete beams after cracking and repaired with the Epoxy Injection. This study used 4 (four) high strength reinforced concrete beams (BBMT) with (15 ´ 30 ´ 220) cm dimention. One of the beam is for comparison (BBMT Normal) and 3 (three) other beams were tested at the age 7 days (BBMT E-7), 14 days (BBMT E-14) and 28 days (BBMT E-28) after repaired. The beams is designed to have flexural failure by using a compression reinforcement and shear reinforcement of 11.9 mm and 15.8 mm for tensile reinforcement. The water cement ratio for mix design is 0,25 obtained at 28 days is 66,62 MPa. The results shows that all the beams have flexural failure in agreement to the early design. The ultimate load of BBMT Normal is 17,65 ton with deflection equal to 10,36 mm. Based on theoretical calculation the load is 16.04 tons and deflection 14.38 mm. BBMT E-7 after epoxy injection ultimate load is 20,89 tons and deflection is 41.99 mm. BBMT E-14 ultimate load 21,79 tons and deflection equal to 44,27 mm. The ultimate load of BBMT E-28 is 25.52 tons and deflection 13.49 tons. The increase of load are 18.36%, 23.46% and 44.59% when compared with BBMT Normal. Based on the observation on the BBMT after epoxy injection, no cracks evident in most of the injected areas, new cracks appearing around the area of initial crack. It is concluded that epoxy injection is capable to increase the capacity of repaired high strength concrete and th flexural strength of the epoxy repaired concrete beams is increase as the age increased. Abstrak: Beton mutu tinggi merupakan salah satu alternatif material konstruksi untuk pembebanan besar. Beton mutu tinggi memiliki sifat yang kaku sehingga rentan terhadap retak. Salah satu metode perbaikan pada retak beton yaitu injeksi epoxy. Penelitian ini dilakukan dengan tujuan untuk mengamati perilaku lentur pada balok beton bertulang mutu tinggi yang diperbaiki dengan injeksi epoxy. Penelitian ini menggunakan 4 (empat) buah benda uji yaitu balok Beton Bertulang Mutu Tinggi (BBMT) dengan ukuran (15 ´ 30 ´ 220) cm. Benda uji pertama sebagai pembanding (BBMT Normal) dan 3 (tiga) benda uji lain diuji sesuai dengan umur perbaikan betonnya yaitu BBMT E-7 (7 hari), BBMT E-14 (14 hari) dan BBMT E-28 (28 hari). Balok didesain mengalami gagal lentur dengan menggunakan tulangan tekan dan tulangan geser berdiameter 11,9 mm ulir serta tulangan tarik 15,8 mm ulir. Kuat tekan beton mutu tinggi yang didapat dari benda uji kontrol kubus sebesar 66,62 MPa dengan FAS 0,25. Hasil penelitian menunjukkan bahwa semua benda uji balok mengalami gagal lentur sesuai dengan desain awal. Beban maksimum yang mampu dicapai oleh balok BBMT Normal adalah 17,65 ton dengan lendutan sebesar 10,36 mm. Perhitungan teoritis beban BBMT Normal yaitu 16,04 ton dan lendutan 14,38 mm. BBMT E-7 setelah diinjeksi menghasilkan beban sebesar 20,89 ton dan lendutan 41,99 mm. Pada BBMT E-14 beban yang dicapai 21,79 ton dan lendutan sebesar 44,27 mm. Beban maksimum pada BBMT E-28 yaitu 25,52 ton dan lendutan 13,49 ton. Masing-masing persentase peningkatan beban jika dibandingkan dengan BBMT Normal adalah 18,36%, 23,46% dan 44,59%. Pola retak yang terjadi pada balok BBMT setelah diinjeksi menunjukkan bahwa tidak terjadi retak pada sebagian besar daerah yang diinjeksi, retak baru muncul di sekitar retak awal. Dapat disimpulkan bahwa injeksi epoxy mampu meningkatkan kapasitas beton mutu tinggi dan umur perbaikan beton mempengaruhi nilai beban maksimum yang mampu dicapai oleh beton.

Abstract

In the design of high and low-rise buildings, structural systems should consider the requirements of strength, stifness, and stability. The addition of bracing affects the stiffness of the structure of the building. In SNI 03-1729-2002 there is an Effective Length Method (ELM) method which only recommends first-order analysis with amplification factor. However, currently there is a new structural design regulation that is SNI 1729: 2015 which refers to the American Institute of Steel Contruction (AISC 2010) where the steel structure stability planning has taken into account the second-order effect directly. This study aims to compare the application of Direct Analysis Method (DAM) and Effective Length Method (ELM) on 2D simple structure, where the comparison of both methods is focused on stress ratio value, which aims to determine more effective and efficient method in designing of braced steel frame structure. The difference values of stress ratio obtained in this study varies from 0.1 to 8.9%, where the value of DAM stress ratio is smaller than ELM. Comparison between the two methods shows that DAM is a more effective method and results in higher profile capacity than ELM.
