Abstract

Design of Paviliun Garuda II  dr. Kariadi Hospital Building, Semarang is designed using the Special Moment Frame System (SMFS). With the election of SMFS system expected to behave ductile structure, because ductile structure not only has large energy but also has a large caapacity in the resist earthquake loads. In system of SMFS, we have to use the concept of strong column weak beam in which the vertical elements of the structure (column) must be made stronger than the horizontal elements of the structure (beam), so that the plastic joints formed first on the beam. In addiction, beam-column joint must also be properly designed to prevent the collapse first. The technique of design and analysis structure, by using the SAP 2000v14 program, will obtain internal forces used to calculate the number of the reinforcements needed by the structure. It is in accordance with Indonesian National Standard or SNI as the main guidance in design of Paviliun Garuda II  dr. Kariadi Hospital Building, Semarang.

Abstract

This research studied the effect of nickel-based cement substitution in concrete to analyze its behavior. The percentage of substituted nickel-slag was 10%, 20% and 30% to the cement weight. The mechanical properties studied were the compression f'c and tensile fMR stresses at the ages of 14, 28, 42 and 56 days. The data were analyzed and the visual observation of the fractured plans were addressed to determine the failure modes. The research concluded that the nickel-slag cement reduced both the compressive and tensile strength as a function of the substituted content, the decrease process followed a linear path. It was found that the strength of nickel-slag concrete cannot be defined at 28 days due to a prolonged chemical process.

Abstract

Bambu merupakan tanaman jenis rumput-rumputan yang mudah tumbuh dengan waktu pertumbuhan yang relatif cepat dan dapat dipanen pada usia 3-4 tahun tanpa harus menanam ulang. Meskipun bambu mempunyai sifat fisik dan mekanik yang baik, tetapi pemanfaatan bambu sebagai material konstruksi masih sangat terbatas. Pengembangan material bambu sebagai material konstruksi diharapkan dapat mereduksi penggunaan kayu yang selama ini telah dieksploitasi secara masif. Paper ini menjelaskan hasil kajian eksperimental material bambu dan papan bambu lapis. Papan bambu lapis tersusun atas tiga layer dan setiap layer terbentuk atas bilah-bilah bambu yang tersusun secara paralel. Layer 1 dan 3 merupakan layer permukaan dengan arah memanjang papan, sedangkan layer 2 merupakan bagian tengah papan yang membentuk sudut a terhadap layer 1 dan 3 yaitu 30°, 45° dan 90°. Hasil pengujian tarik menunjukkan bahwa semua bilah bambu berperilaku getas, bagian luar mempunyai kekuatan dan kekakuan yang lebih tinggi dibanding bagian dalam dan ruas bambu merupakan perlemahan dari bilah bambu. Pengujian lentur papan bambu lapis dilakukan dengan four point bending, kapasitas dan kekakuan papan bambu lapis dipengaruhi oleh sudut a dengan nilai optimal 29,33°. Sedangkan kekakuan lentur rata-rata papan bambu lapis sebesar 71% dari penampang teoritis dengan dimensi yang sama untuk bilah bambu luar.

Abstract

In the process of architectural design, there is no special method employed by architects to evaluate buildings’ structural vulnerability and building geometry form designs towards earthquakes. Therefore, the alternative is adapting the existing method called SVA-Retrofit. JBDPA and Matsutaro Seki developed this method, and then the author adapted this method now called SVA Architectural Design. In the process of adaptation, deep literature review was conducted in order to acquire the adaptation results of the SVA-Architectural Design. These results can furthermore be an early prediction of structural vulnerability toward earthquakes that eventually leads to finding solutions for building designs or conducting detailed analysis done by structure experts.

Abstract

Situated at an earthquake prone area, buildings planning in Indonesia must implement earthquake resistant building principles. One of these principles is determining dimensions of columns and beams in the process of architectural designing.This act eventually affects the behaviour of the strong column-weak beam and the probability of bending failure due to soft story. At present time, there are no simple rules architects can use in calculating the dimensions of beams and columns that meet the criteria for strong column-weak beam and non-soft story. This paper is an effort to provide an input to the architects in designing the dimensions of the columns and beams. This research is a review result of three theories namely: 1). The theory of columns and beams preliminary design, 2). The theory of the strong column-weak beam concept, and 3). The theory of soft story and column slenderness. Those theories were then synthesized into a spreadsheet. To meet the criteria for strong column-weak beam and non-soft story, the following procedures must be done : 1). Determine the columns’ dimensions according to 0.15% of the columns’ cumulative tributary area, 2). Determine the beams’ dimensions according to 1/12 of the beams’ span and the beams’ plastic modulus, 3). Determine the columns’ dimensions and the columns’plastic modulus, 4). Determine the columns’ height based on the column slenderness criteria, and 5). Compare the columns plastic modulus and the beams plastic modulus and check whether they meet the criteria “the columns’plastic modulus ≥ 1.2 * the beams’ plastic modulus”.

Abstract

Gedung Ex. Mega Eltra merupakan salah satu gedung konservasi di Semarang yang dibangun pada sekitar tahun 1857-1860 dan telah mengalami kerusakan struktur yang parah akibat pengaruh lingkungan, penurunan muka tanah, dan cuaca. Namun, serangan air laut terhadap degradasi material khususnya kekuatan beton menjadi perhatian dalam penelitian ini. Penurunan muka tanah di kota lama Semarang membuat bangunan mengalami penurunan pada fondasi, bahkan sering sampai di bawah permukaan tanah sekitar yang membuat bangunan terendam. Genangan air pada bangunan yang memiliki kandungan salinitas, klorida, dan sulfat dapat menurunkan kekuatan beton melalui kapilaritas dan kontak langsung dengan udara yang tercemar klorida dan sulfat. Tiga lokasi kolom beton Lantai-1 dan 2 dibor dengan mata bor 50 mm hingga kedalaman kurang lebih 225 mm dari permukaan kolom. Bore log 225 mm dipotong menjadi tiga buah benda uji yang mewakili bagian luar, tengah dan bagian dalam, selanjutnya benda uji tersebut diuji untuk mengetahui kuat tekan beton. Hasil uji kuat tekan menunjukkan bahwa beton Lantai-2 lebih baik dari Lantai-1, dan kuat beton bagian luar lebih kecil dari pada bagian tengah, dan jalur tengah lebih kecil dari pada bagian dalam. Penurunan kekuatan beton akibat kontaminasi klorida dan sulfat dapat terjadi melalui kontak udara dan kapilaritas. Pengaruh air laut terhadap penurunan kuat beton melalui kapilaritas adalah 23,51 % dan penurunan kuat beton m­­­­­­elalui udara pada Lantai-1 210 % lebih kuar dibanding Lantai-2.
