"Tujuan utama dari penelitian ini adalah untuk mengobsevasi dan membandingkan perilaku dari bermacam tipe sambungan antara papan penutup dan rangka kayu yang merepresentasikan bagian dari shear wall kayu. Setiap sampel kemudian dibandinkan berdasarkan beberapa parameter antara lain: strength limit state, yield limit state, energi terdisipasi, dan ductility ratio. Eksperiment ini dilaksanakan mengacu pada ASTM E2126 dan ISO 16670 Loading Protocol dan tes kuat tarik terstandar. Terdapat 5 macam koneksi yang di amati: 1) paku dengan jarak interval 50 mm, 2) paku dengan jarak interval 100 mm, 3) staple dengan jarak interval 25 mm, 4) staple dengan jarak interval 50 mm, dan 5) menggunakan perekat kayu standar. Hasil dari test tersebut kemudian dibandingkan menggunakan metode statistik meliputi descriptive statistics¸F-Test, dan T-Test. Hasil dari perbandingan tersebut mengungkapkan bahwa semakin besar jarak interval antar sambungan akan menurunkan performa dari struktur sambungan antara papan penutup dan rangka kayu. Hal ini didukung dengan nilai P yang dihasilkan saat membandingkan setiap sample yang bernilai lebih rendah dari 0.01. Selain itu, hasil perbandingan antara sambungan paku dan staple menggunakan F-Test dan T-Test menemukan bahwa ada kemungkinan untuk mensubstitusikan paku dengan staple dikarenakan nilai P yang di hasilkan sangat dekat dengan 0.1. Akan tetapi, penelitian lebih lanjut sebaiknya dilakukan untuk membuktikan konsistensi hasil ini. Temuan lainnya adalah performa dari sambungan antara papan penutup dan rangka kayu berkurang sebanyak 32% pada cyclic loading test dibandingkan dengan hasil pada tes kuat tarik. Sayangnya, hasil eksperimen terhadap sambungan perekat kimia tidak dapat di analisis karena sampel yang bergeser selama pengujian

The objective of this research is to observe and compare the behaviour of the different types of connection between the sheathings and timber section that reassemble the part of timber shear wall of the sheathing-to-framing connection. The comparison of each type of sample is based on few performance parameters such as strength limit state, yield limit state, failure limit state, energy dissipated, and the ductility ratio. The test is conducted in accordance with ASTM E2126 and ISO 16670 loading protocol and a standard monotonic test. On the test, one sample will be tested on the monotonic loading test while the rest (4 samples) are tested on cyclic loading test. There are 5 variations of the sheathing-to-framing connection that being tested: 1) nails on 50 mm interval, 2) nail on 100 mm interval, 3) staple on 25 mm interval, 4) staple on 50 mm interval, and 5) glue connection. The result of the test then compared using statistics method including descriptive statistics, F-Test, and T-test. The result of the comparison shows that the increment of the connection interval will significantly reduce the performance of the sheathing-to-framing connection. It is supported by the fact the P value produced while comparing each sample with different interval is less than 0.01. It was found that there might be a possibility to change nail connection with staple, this is supported by the fact the P value on comparison between nail on 50 mm interval and staple on 25 mm interval is close to 0.1. However, further study should be conducted to prove its consistency. This study also found that the hysteretic performance of sheathing-to-framing in cyclic loading test is reduced by 32% in contrast to the monotonic result. Unfortunately, the result from the glue connection on cyclic testing could not be analysed due to damaged data caused by slipping sample."

"Perkembangan teknologi pembangunan kapal dari masa ke masa terus mengalami kemajuan seiring dengan adanya penemuan metode konstruksi baru yang modern dan canggih untuk mendapatkan hasil yang lebih efisien dari segi waktu dan harga. Keadaan ini berlawanan dengan pembangunan kapal berbasis kerakyatan, dimana proses pengerjaanya masih bersifat tradisional serta membutuhkan waktu yang relatif cukup lama khususnya pada kapal pinisi.
Kapal pinisi menggunakan bahan dasar kayu,dimana keberadaanya semakin terbatas dan mahal. Maka dari itu,dengan misi untuk menyelamatkan pelayaran rakyat khususnya kapal pinisi. Mulai saat ini sudah perlu dipikirkan dan dicari bahan baku alternatif untuk mengganti kayu sebagai bahan baku pembuatan kapal dengan bahan baku lain. Salah satu cara yang digunakan ialah dengan memakai teknologi laminasi yaitu dengan menggabungkan satu atau lebih jenis material yang direkatkan menjadi satu kesatuan.
Dalam skripsi ini, metode yang dipakai adalah analisis dari sampel kapal pinisi yang telah dibangun. Batasan analisis yang penulis ambil hanya pada konstruksi saja khususnya pada bagian lambung kapal. Oleh karena itu, melalui teknologi laminasi ini diharapkan mendapat material yang memiliki karakteristik mekanik yang lebih baik, bobot yang lebih ringan serta harga yang relatif murah serta mempermudah pengerjaan dalam proses pembangunan kapal baru.

The development of shipbuilding technology from time to time continue to progress along with the discovery of new, modern construction methods and technology to get more efficient results in terms of time and price. This situation is contrary to populist-based ship building, where the working process still traditional in nature and require a relatively long time, especially on pinisi ship.
Pinisi ship using basic materials of wood, where its presence is increasingly limited and expensive. Therefore, with a mission to rescue the people, especially cruise ship pinisi. Start now to think about and look for alternative materials to replace wood as raw material for the manufacture of ships with other raw materials. One method used is by using lamination technology by combining one or more types of material bonded into a single unit.
In this paper, the method used is the analysis of samples pinisi ship that has been built. Restriction analysis that the authors take only on construction alone, especially on the hull. Therefore, through lamination technology is expected to have material that has better mechanical characteristics, the lighter weight and a relatively cheap price and makes for progress in the development process of new vessel.

"Dewasa ini, penggunaan material komposit sebagai elemen dalam struktur bangunan berkembang dengan pesat. Pada kesempatan ini kami meneliti penggabungan antara kayu dengan baja menjadi komposit kayu-baja yang diimplementasikan sebagai elemen balok. Balok kayu yang digunakan berpenampang rectangular, sedangkan profil bajanya dari siku yang diletakkan terbuka pada sisi atas dan bawah balok kayu. Penelitian ini bertujuan untuk mengetahui seberapa jauh manfaat dari pemberian tambahan material baja ternadap kekuatan kayu. Kesulitan yang timbul selama penelitian adalah mendapatkan data yang cukup lengkap tentang sifat fisik dari jenis kayu yang digunakan dalam studi eksperimen, oleh sebab itu dilakukan serangkaian uji awal temadap sampel yang akan digunakan dalam eksperimen untuk mendapatkan data sifat fisiknya, dan melakukan beberapa asumsi untuk melengkapi kebutuhan data.
Metode numerik yang digunakan untuk melakukan perhitungan kekuatan penampang adalah dengan membagi penampang menjadi serat-serat dengan ketebalan yang tipis, atau disebut fiber model. Dari serat-serat ini kemudian dihitung tegangannya berdasarkan hubungan tegangan-regangan material. Hubungan tegangan-regangan kayu dan baja diasumsikan sebagai kurva bilinier dengan adanya penambahan kekuatan setelah kayu melewati titik lelehnya. Pendistribusian regangan diambil asumsi bahwa regangan akan terdistribusi secara linier dan sifat non-linearitas penampang diabaikan. Dari hasil perhitungan ini, kemudian didapatkan hubungan antara momen kapasitas penampang dengan kurvatur. Selanjutnya dilakukan interpolasi untuk mendapatkan hubungan antara momen gaya dalam dengan kurvatur. Setelah mendapatkan hubungan ini, maka dapat dihitung berapa rotasi dan defleksi yang terjadi pada balok.
Hasil dari perhitungan numerik ini adalah kurva beban-lendutan untuk balok kayu non-komposit dan komposit. Dari hasil analisis numerik, maka kemudian dilakukan perbandingan dengan hasil eksperimen. Berdasarkan hasil eksperimen, pada tiap sampel yang diuji, ternyata terdapat bentuk keruntuhan yang berbeda dari asumsi awal, yaitu adanya kegagalan geser pada kayu, local buckling pada profil baja atas, serta slip pada shear connector. Oleh karenanya, dilakukanlah perhitungan reduksi kekuatan pada baja agar lendutan dari perhitungan numerik yang didapatkan lebih sesuai dengan hasil eksperimen. Hasil akhir dari analisis tersebut adalah kurva beban-lendutan yang sudah tereduksi yang dibandingkan dengan hasil eksperimen serta kesimpulan terhadap hasil penelitian balok komposit kayu-baja ini.

Nowadays, the use of composite material is growing rapidly. In this opportunity, we study the combination of wood and steel to become the wood - steel composite which implemented as a beam element, the wood beam that is used in this study is a rectangular profile, and for the steel is an L type profile. This studies objective is to know the advantage that can be obtain by using additional steel material to the strength of wood beam. There are some difficulties that happened in this research; some of those are that we don't have enough literate material that we need to know about the physical characteristic of wood, and the lack of data about wood - steel composite. Because of that, we have to make some assumptions based from the experimental studies.
The numerical methods that is used to count the strength of the profile is by dividing the profile into a thin fiber, this method is known as the FIBER MODEL. From this fiber, we then calculate the strain using the strain - stress relation of the material. From this calculation we now have the profile's axial force and moment capacity. And then, we make an interpolation between the moment capacity, curvature, and moment form loading. After we have the relation of moment and curvature, then we can calculate the rotation and deflection which happened in the beam.
The result of this numerical calculation is the load - displacement curve, where we can compare it to the result from the experimental studies. Using this comparison, then we can make analysis of the composite material. Composite beam structure is approved to be the reason of the increasing number of strength, stiffness, and ductility.
