Abstract

In case of building structure plan, analyzing of earthquake effect is important. Especially for building which located in big earthquake zones. Indonesian isles are situated on major earthquake zones. That’s why the good planning are needed to manage earthquake risk to avoid big accident. On this final paper, the building are planned with Sway Special Design System. That based on SNI 03-2847-2002 and SNI 1726-2010.  “Strong Column Weak Beam” concept is used for the building. The planning of structure are consist of 14 levels and 2 basements which located in 3rd earthquake zone. We expected that Sway Special Design System can be good applicated and useful for all of people on building plan which located in major earthquake zone.

Abstract

Separated Highway Casablanca Package is located at Kuningan, Jakarta. This separated highways is designed using prestressed concrete box girder construction. The erection method is conducted by means of balance cantilever method. The main equipment used in the erection of box girder is launcher gantry. Total length of the separated highways is 1175 m, which is divided into 24 spans. This separated highways has 25 piers. The first step of designing this separated highway is by designing the dimension of the box girder. The next step is analyzing the loads that are predicted to work on the structure, namely load, traffic load, wind load, and earthquake load. Next, structural analysis is carried out to obtain the internal forces and stresses in the structure. The result of the structural analysis is used to calculate loss of prestressing force, needs of tendon, and the reinforcement of box girder. The next step is designing Piers and Foundation. The reinforcement in the piers is 1,33 times of the minimum reinforcement required by analysis. The Foundation uses bore piles and calculated using Broms method.

Abstract

Kaligung Bridge is located in Tuwel village of Slawi in Tegal regency. The Bridge connects Bumijawa and Tuwel area and stretches along 70 meters above Kaligung river. In this project, Kaligung Tuwel bridge was designed as a steel truss system. The design steps are as follows : analysis of the existing conditions, design the upper structure and the substructure of the bridge, and calculate budget plan (RAB). The Design of the upper structure considers loads such as : self weight, dead load, traffic load, wind load, and seismic load. The design was carried out using LRFD (Load and Resistance Factor Design) method. Next, the substructure was designed by calculating the dimension of the foundation and abutment. The foundation was designed as a caisson while the abutment wasof cantilever type.

Abstract

It is well known that compressive strength of concrete is affected by the strength of the constituent materials and the strength of interfacial transition zone (ITZ). This research aimed at investigating the influence of the addition of resin on coarse aggregates on the strength of concrete. The resin investigated in this research was unsaturated polyester resin. The resin was combined with methanol with different composition of 1:0; 1:0.25; 1:0.5; and 1:1. The tests conducted in this investigation were pull off test, shear test and compression test. Test results show that all specimens with resin exhibit lower strength values compared to specimens with no resin. The compressive strength of concrete silinders with resin coated aggregates were obtained to be 16.26 MPa and 3.14 MPa, while the compressive strength of normal concrete ( with no resin) was 29.99 MPa.

Abstract

This research aimed at investigating the effect of glass thickness on the strength of annealed glass panels. The research was conducted using both experimental tests and numerical simulations. The experimental tests were conducted using the double ring method, while the numerical simulations were carried out using Finite Element Method (FEM). Numerical simulations were conducted first to determine efficient meshing, dimension of the specimen, and the equipment capacity. The number of specimens were 400 with the same width and length of 200 mm x 200 mm. The thickness of which were varied from 3 mm up to 10 mm. The test results were maximum load and fracture origin. Both of these results were used to calculate the strength of the glass that was expressed as failure stress at the location of fracture origin. The failure stress scattered in a wide range, hence statistical analysis was required to analyze the glass strength. From the analysis, it can be seen that the strength of glass was affected by its thickness. Some graphs have been created to show the allowable pressure that can be resisted by certain dimension of glass panels.

Abstract

Design of highrise building includes design of structure elements such as floor slabs, stairs, beam-column frames and foundations to withstand all working loads. Therefore, an engineer should select the most appropriate structural system such as fully elastic, partially ductile or fully ductile. The structure of Horison Hotel Pekalongan is designed to apply Special Moment Resisting Frame System (SRPMK) based on Indonesia building codes and standard. The structure analysis was conducted using ETABS v.9.7.1 software. The seismic analysis using the response spectrum dynamic analysis obtained the value of maximum vibration period of 1.74 seconds and design seismic force (V) = 344.18 ton. The internal forces calculated from ETABS v.9.7.1 were used to determine the amount of reinforcement required by the structure. Results obtained from the design show that Special Moment Resisting Frame System (SRPMK) used in Horison Hotel Pekalongan is capable of supporting all working loads considered in the analysis.

Abstract

Sektor konstruksi mempunyai peran penting dalam menggerakkan sektor riil dan meningkatkan pertumbuhan ekonomi dengan menciptakan lapangan kerja dan peningkatan produktivitas serta daya saing konstruksi. Untuk itu diperlukan adanya kebijakan – kebijakan yang mengatur tentang hal – hal yang mempengaruhi produktivitas (5M) terutama pada bidang konstruksi sehingga terjadi peningkatan produktivitas yang secara tidak langsung akan meningkatkan daya saing infrastuktur. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pola kebijakan produktivitas konstruksi Indonesia terhadap daya saing infrastruktur berdasarkan data – data seperti UU Jasa Konstruksi, UU Ketenagakerjaan, Peraturan Presiden, Peraturan Menteri ,Peraturan Daerah dan Standar Nasional Indonesia (SNI) beserta data – data sekunder seperti jumlah penduduk Indonesia, jumlah tenaga kerja konstruksi, jumlah tenaga kerja konstruksi ahli dan terampil, nilai konstruksi yang diselesaikan dan proyek strategis nasional yang dikeluarkan oleh Badan Pusat Statistik (BPS). Untuk mengolah data – data tersebut dipakai metode penelitian yang digunakan adalah analisis deskriptif dan metode Crosstab. Kesimpulan dari penelitian ini adalah kebijakan – kebijakan yang dibuat pemerintah dalam hal produktivitas konstruksi secara tidak langsung berpengaruh terhadap daya saing insfrastuktur seperti semakin meningkatnya nilai konstruksi yang diselesaikan, semakin banyaknya proyek stategis nasional yang rampung  sesuai dengan tahun pengoperasian dan peningkatan tenaga kerja konstruksi yang bersertifikasi.

Abstract

Jembatan Penyeberangan Orang (JPO) dengan bentang panjang dan JPO dengan lantai bertingkat, mulai banyak di bangun di kota-kota besar di Indonesia. JPO dibangun sebagai sarana penghubung dari satu bangunan ke bangunan lainnya, sekaligus berfungsi sebagai jembatan penyeberangan lalu lintas yang berada di bawahnya. Bentuk struktur yang langsing membawa konsekuensi, bahwa struktur JPO rentan terhadap masalah getaran. Masalah munculnya getaran pada struktur JPO pada saat orang melewati jembatan, akan menyebabkan ketidak-nyamanan bagi pengguna jalan. Getaran yang muncul pada JPO dapat diakibatkan oleh karena frekuensi getar alami dari struktur JPO yang terlalu besar, atau terjadinya resonansi yang diakibatkan karena frekuensi getar beban yang melewati JPO mendekati frekuensi getar alami dari struktur. Pada perencanaan struktur JPO, asumsi bahwa beban pejalan kaki merupakan beban statik dengan hanya satu arah komponen beban kearah vertikal, adalah tidak tepat. Beberapa penelitian telah membuktikan bahwa beban orang yang bergerak merupakan beban dinamik yang mempunyai tiga komponen arah beban, yaitu arah vertikal, longitudinal, dan lateral. Dari hasil penelitian diketahui bahwa, beban pejalan kaki yang bersifat dinamik pada struktur JPO 2 Lantai, akan menyebabkan deformasi struktur 1,55 kali lebih besar  dibandingkan dengan deformasi yang didapat dari analisis statik. Hal ini kiranya perlu diperhatikan di dalam perencanaan struktur JPO, agar didapatkan perencanaan yang memenuhi syarat kekuatan dan kekakuan, sehingga tidak menyebabkan terjadi permasalahan getaran pada saat digunakan.
