Abstract

Panels  in wooden construction serve as walls as well as providing structural lateral  resistance  against  earthquake  if  designed well. Panel materials  consist of frames with  sheathings  such  as  Plywood  or Oriented Strand Board(OSB)  connected  to  wooden  frames with nails as connectors. Lateral force of the panels can be increased, for example by adding diagonal rods/bracings to the frames. In this study a wooden  panel which was Sengon wooden panel connected to Laminated Veneer Lumber(LVL) wooden panel with CN 50 nails with  a diameter of 2,8 mm and  the distance between  the nails was 240 mm with plain  steel  reinforcement  single bracing with a diameter of 8 mm in pull position using corner plate as a connector between bracing and LVL wooden panel. Cyclic  test had 20%Δy,  40%Δy,  60%Δy  deformation controls  and  loaded with monotonic  until wooden panels collapsed. The  results of cyclic  test  in  stable  condition  60%Δy had equivalent viscous damping ratio values of 8,324%.  Failures  in  panels  often  happened  to  connecting  nails,  corner  plates,  and steel  bracings. The  types  of  failure were Nail  Pull-Through  of  Sheathing,  Pull-Through  Sheathing  Failures,  Mudsill  Failure,  buckling  on  corner  plates,  and buckling on steel bracings

Abstract

Self Compacting Concrete (SCC) is concrete with high fluidity so that it can flow and fill the spaces in the mold without the compaction process. This study discusses the effect of the adding of kaolin and polypropylene fibers in order to increase the flowability, compressive strength, flexural strength, and tensile strength in self-compacting concrete. The additional material of kaolin was 5%, 10%, and 15% of the cement weight. The polypropylene fibers were 1%, 1.5%, and 2%. The flowability test, which was used, was Table flow, V-Funnel, and L-Box. Compressive strength testing was conducted when the concrete was 7, 14, and 28 days old. The flexural test was performed with a measurement of 150 x 150 x 600 mm as many as 18 specimens tested at the age of 28 days. The results showed that the addition of kaolin and polypropylene fibers met the flowability specifications of self-compacting concrete. The addition of polypropylene can increase the flexural strength and tensile strength of the concrete beam, but cannot increase the compressive strength of self-compacting concrete.

Abstract

Mitra pada program pengabdian ini adalah masyarakat Dukuh Butuh Kidul, Sedayu, Bantul, Yogyakarta. Masalah yang dialami mitra yaitu tidak tersedianya fasilitas wudu pada musala, sehingga warga harus berwudu di rumah warga yang berada di sekitar Musala. Sebagai pusat ibadah khususnya salat, maka Musala terkait dengan permasalahan syarat sahnya salat antara lain berwudu dan suci dari najis sehingga diperlukan jaminan sahnya wudu para jamaah serta kesucian musala. Maka dari itu, dalam program Pengabdian Kepada Masyarakat yang dibiayai oleh LP3M UMY Tahun 2019/2020 kami bersama dengan Mahasiswa Himpunan Sipil (HMS) UMY melaksanakan pengabdian masyarakat berupa pembangunan fasilitas wudu dan toilet pada Musala Dukuh Butuh Kidul. Metode yang digunakan dalam pembangunan tempat wudu dan musala ini mengacu pada panduan pembangunan perumahan dan permukiman perdesaan yang dikeluarkan oleh Kementrian Pekerjaan Umum dan Perumahan Rakyat. Karena adanya keterbatasan dana hibah pengabdian maka program yang telah dilaksanakan dalam pengabdian ini yaitu berupa pembuatan fondasi, sloof, dan kolom. Untuk tindak lanjut pada periode pengabdian yang akan datang akan dilaksanakan pekerjaan dinding, lantai, atap, sanitasi, dan plumbing.

Abstract

Buildings have an essential function; they are a place for people to carry out various activities, such as social, economic, and religious activities. In a building construction plan, considering multiple factors from strength to architecture is necessary. The issue of limited land in some areas has resulted in the construction of vertical buildings, often known as high-rise buildings. High-rise building construction requires paying attention to various levels of vulnerabilities, especially for projects in earthquake-prone areas. In this study, the levels of vulnerability and vertical irregularity of high-rise buildings were analyzed based on structural rigidity for reinforced concrete structures. Building models including a cube-shaped model, L-shaped model, and U-shaped model were investigated. The STERA 3D program was used to determine the strength values of the structures by providing earthquake loads on each structure model using the time-history analysis method. The El Centro and Kobe earthquakes were tested in these structural models because the earthquakes are known to contribute the most exceptional damage value in the history of earthquake-caused disasters. The assessed parameters of the tested structural models include structural stiffness, the most significant displacement in the structure, the maximum displacement and load relations experienced by the construction, and the hysteretic energy exhibited by the structure. Therefore, the best performed structural model in resisting the load could be obtained. The results showed that the U-shaped building model had the highest stiffness value with an increase in stiffness of 7.43% compared with the cube-shaped building model and 3.01% compared with the L-shaped building model.

Abstract

Concrete is considered one of the construction materials that contribute the most significant carbon dioxide in the world. Meanwhile, according to various studies, concrete production will continue to rise through 2050, especially in developing countries. According to several reports, cement manufacture is one of the largest sources of carbon dioxide in the concrete sector. In addition, overexploitation of aggregates due to concrete production also causes unavoidable natural damage. Bottom ash waste was used as a replacement for cement and fine aggregate as sustainable construction materials. It is envisaged that this research would allow industrial waste to be utilized to its full potential, resulting in a concrete that is more environmentally friendly and minimizes carbon dioxide emissions during the manufacturing process. This study is divided into bottom ash as a cement substitute and bottom ash as a fine aggregate substitute. The engineering properties of the concrete were checked during the experiments in this study when it was fresh and hardened states. The slump test is used to determine the workability of fresh concrete. While for the hardened properties tests consist of compressive strength, splitting tensile strength, flexural strength, and mass density. The usage of bottom ash as a cement replacement demonstrates that as the composition of bottom ash increases, the performance of the hardened properties of concrete decreases. While using bottom ash as a fine aggregate replacement reveals that the performance of hardened properties has improved as the proportion of bottom ash utilized has increased. Doi: 10.28991/CEJ-2022-08-01-014 Full Text: PDF
