Abstract

Innovation in obtaining construction materials that are efficient and applicable to various conditions is a challenge for researchers. Cold-formed steel is a material breakthrough in construction that has advantages over hot-rolled steel. Many studies have been carried out on Cold-formedsteel subjected to various loadings to examine the behavior and capacities of the sections. This study aims to investigate the behavior and section capacity of cold-formed steel unlipped channels due to axial compression loads. This research begins with conducting a literature study, then carrying out numerical analysis using the finite element method in ABAQUS, numerical test, and calculation of section capacity based on existing research in the literature. The calculation of section capacity is carried out based on SNI 7971-2013 or AS/NZS 4600:2005. The results of the numerical analysis can be seen from the behavior and capacities of the sections of the unlipped channel, the section capacity from the numerical test will be compared with the section capacity obtained from the calculation based on SNI 7971-2013 or AS/NZS 4600.

Abstract

Design changes are inevitable in most projects. In many construction projects they may look not too complicated to be executed in front of computer models. The actual situation turned out to be the other way around. Apart from detailed changes in shop drawings, bill of quantity and specifications, administrative works related to the project are quite considerations. These mounted consequences would be more for short duration projects with government funding executed in the near end book period. The allocated execution period for short duration projects is not usually allowing rapid changes for the unexpected consequences. This paper presents what actually happens inside the project management during the contract change order process.

Abstract

Pembangunan sarana ibadah seperti mushola memiliki peran strategis dalam mendukung kehidupan sosial dan spiritual masyarakat, sehingga bangunan yang menjadi tempat berkegiatan orang banyak harus dibangun sesuai standar yang berlaku. Permasalahan yang sering terjadi adalah banyaknya bangunan umum termasuk mushola yang dibangun tanpa pendampingan tenaga ahli Teknik Sipil, sehingga sering mengabaikan proses penyelidikan tanah. Kurangnya pemahaman masyarakat terhadap pentingnya uji tanah dalam proses pembangunan, sehingga banyak bangunan yang didirikan tanpa mempertimbangkan karakteristik tanah di lokasi, dan berisiko menimbulkan kerusakan struktural di kemudian hari. Pegabdian dengan memberikan penyuluhan tentang pentingnya penyelidikan tanah, penyediaan teknis penyelidikan tanah serta pendampingan teknis yang berkelanjutan. Pengabdian ini bertujuan memberikan kontribusi nyata bagi pembangunan mushola yang aman dan fungsional
