Abstract

This study discussed the H and WF steel profiles that encountered axial compressive forces. A structural element with a straight geometry was loaded by axial compressive forces which is started from 1 N until the highest load that could be achieved. This simulations was done by finite element method program of Ansys R18.0. In this study, an analysis of the H and WF steel profiles was carried out to obtain failure conditions and the value of buckling load that can be achieved from the steel profile with variations in type of restraints. The buckling load analysis is carried out theoretically (literature) and compared with eigenvalue buckling by Ansys R18.0. The buckling load generated by Ansys R18.0 will also be analyzed to obtain the effective length conversion factor (K) and then compare it with the K value got from the existing literature.The results showed both H and WF steel profile underwent failure by flexural buckling conditions, meanwhile the largest buckling load is 1.452,5729 kN of H 200x200x12x8 profile with fixed-fixed type of restraints, and the smallest buckling load was found 1,7639 kN of WF 100x50x7x5 profile with fixed-free type of restraints by the theoretical analysis. The effective length conversion factor (K) by using Ansys R18.0 was found 6% smaller than the existing literature. The buckling loads calculated by Ansys R18.0 was found 12% greater than the results of theoretical analysis

Abstract

Perhitungan manual dalam analisis struktur terbilang rumit, menghabiskan waktu yang lama, dan rentan terjadi kesalahan dalam proses perhitungan. Meskipun sudah ada program analisis struktur yang canggih, tetapi belum tentu pengguna dapat mempelajari cara penggunaan program tersebut dengan mudah dan cepat. Oleh karena itu, dalam tulisan ini dirancang program analisis struktur untuk portal bidang. Tujuannya yaitu untuk membuat program yang diharapkan dapat user friendly sehingga dapat membuat pengguna lebih mudah dalam mempelajari dan menggunakan program tersebut. Program yang dirancang dalam tulisan ini menggunakan metode matriks kekakuan langsung. Program dibuat mengunakan aplikasi MATLAB R2017a dengan tampilan APG (Antarmuka Pengguna Grafis). Kemudian program diuji melalui dua contoh kasus, di antaranya struktur portal 3 batang dan struktur portal 2 lantai. Selain itu, program telah dibandingkan dengan SAP2000 v14. Dalam program ENDSTRIS ini, beberapa fitur yang dibuat yaitu perhitungan reaksi perletakan, gaya-gaya batang, deformasi (perpindahan dan rotasi), diagram momen, diagram geser, diagram normal dan garis elastisitas. Hasil analisis yang didapatkan dengan menggunakan ENDSTRIS tidak berbeda dengan hasil yang didapatkan dengan menggunakan perhitungan SAP2000 v14.

Abstract

Pusat Ziarah Keluarga Kudus Nazaret Sa’pak Bayobayo Toraja (PZKKN-SBT) pertama kali diresmikan oleh Uskup Agung Makassar pada tanggal 03 Juli 2018. PZZKKN-SBT menghadirkan wisata rohani yang dengan paket lengkap. Namun demikian, terdapat kendala terkait dengan layanan air yang ada pada PZZKKN-SBT, belum memenuhinya ketersediaan air baik dari segi kuantitas maupun kualitas merupakan salah satu masalah yang harus segera diselesaikan. Oleh karena itu, perlu adanya rancangan instalasi penjernihan air dan jaringan distribusi yang memadai untuk melayani kebutuhan air yang ada di PZZKKN-SBT guna mendukung fasilitas yang diberikan kepada wisatawan pada saat mengunjungi PZZKKN-SBT. Pada kegiatan pengabdian ini, dibuat rancangan instalasi penjernihan air dan jaringan distribusi air dengan menggunakan teknik mekanik serta penggunaan energi terbarukan yaitu dengan memanfaatkan teknologi solar cell yang sedang marak digunakan sebagai salah satu cara untuk mendapatkan energi listrik guna memenuhi kebutuhan air yang ada di PZZKKN-SBT.

Abstract

Nowadays, the use of applications which is to analyze or to design in civil engineering are necessary. Besides being able to solve the analysis and design problem, the use of applications is an effective for computational time problems compared to manual calculations. Column is one of the most crucial elements in a building construction where the role of the column is to support and distribute the loads on the building structure. In general, in designing a column, column interaction diagram with a certain cross section is made and compare the capacity of the column sections (Pn and Mn) from the column interaction diagram with the required strength values (Pu and Mu). Android is an operating system on smartphones and is popular nowadays. The aim of this research is to develop an Android-based application using Android Studio with Java programming language to create a column interaction diagram of several types of columns, i.e. square column with 4 (four) side reinforcement, square column with reinforcement on 2 (two) sides, and circular columns. The results obtained from the developed application are compared with manual calculations (reference). The difference of result obtained is less than 1% which means that there is no significant comparison between the designed application and manual calculations (reference). Therefore, the developed application can be practically used as an alternative in designing columns.
