Abstract

Eccentrically Braced Frames (EBF) merupakan struktur baja tahan gempa yang memiliki kapasitas geser  dan  daktilitas  yang  baik. Struktur  EBF  menjadikan  link  sebagai  elemen yang mengalami kerusakan terlebih dahulu dari elemen lainnya. EBF mempunyai 2 tipe link, yaitu link vertikal dan link horizontal. Link horizontal EBF berotasi ke arah vertikal pasca terjadi gempa besar sehingga mengganggu elemen lain di atasnya dan sulit melaku- kan perbaikan atau penggantian link, solusinya digunakan link vertikal yang memungkin- kan  untuk  perbaikan  atau  penggantian  link,  tanpa  mengubah  bagian  balok.  Dilakukan analisis berupa struktur gedung 10 lantai dengan sistem struktur EBF link vertikal meng- gunakan software SAP 2000 berupa analisis linier dan non  linier.  Selanjutnya dilakukan analisis beban siklik untuk spesimen frame 1 lantai sistem struktur EBF link vertikal meng- gunakan  software  Abaqus  CAE.  Hasil analisis  menunjukkan  bahwa pemodelan  struktur gedung EBF 10 lantai dan spesimen frame EBF 1 lantai mengalami kegagalan elemen terle- bih  dahulu  terjadi pada  link, hal ini  sesuai  dengan konsep  struktur Eccentrically  Braced Frames (EBF).

Abstract

Indonesia is an archipelago that is flanked by oceanic plates and land plates that cause the two plates to often collide. This causes Indonesia to be an earthquake-prone area and has many volcanoes. Research related to earthquakes in Indonesia continues to develop. This has resulted in several points such as new earthquake hazard maps and the latest regulations related to earthquake-resistant building planning, resulting in the building planning process having to follow the latest applicable regulations. The purpose of this study is to analyze changes in SNI, structural dimension requirements, reinforcement requirements, and structural behavior and internal forces due to the application of SNI 1726:2012 and SNI 1726:2019 in a building. The research method used was to conduct a literature study on the changes from SNI 1726:2012 to SNI 1726:2019 using the SNI 2847:2019 planning which will be used in the structural analysis. The results obtained from this study show that there are differences in the earthquake maps used in SNI 1726:2012 and SNI 1726:2019, there are differences in parameters in SNI 1726:2012 and SNI 1726:2019 which result in an increase in the forces acting on the structure which affects the need for reinforcement. Structural planning is carried out by following SNI 1726:2019 and SNI 2847:2019, for existing buildings that have been built based on SNI 1726:2012, it is necessary to carry out a re-examination or assessment to determine the condition of the existing building in relation to earthquake in Indonesia.

Abstract

Strengthening is needed to restore structural capacity such as installing GFRP. This research aims to analyze the flexural strength of reinforced concrete beams using the Abaqus 2017 finite element program, experimental and theoretical results, in the form of maximum load, maximum moment and crack patterns. The research object uses secondary data from experiments by Djamaluddin (2011) in the form of five beam variants, namely normal beams without GFRP, beams with 1 layer of GFRP along the span, beams with 1 layer of GFRP along the span plus 2 layers in the middle of the span, beams with 3 layers of GFRP along the span, and 3 layers of GFRP beams along the span plus 2 layers in the middle of the span. Researchers modeled the five beam variants in the Abaqus program and carried out theoretical calculations. Analysis of the three methods showed that the more layers of GFRP installed, the greater the maximum load and maximum moment. There are differences in the values of the three methods which are possible because the bonding (gluing) is less than perfect in installing the GFRP, and the distribution of the elements (meshing) of the model in Abaqus is less dense so that the stress distribution is less even. Apart from that, it was also seen that there was no difference in the crack pattern between the experiment and Abaqus, namely that the crack pattern in all models started from the middle of the span and then spread along the span.

Abstract

Eccentrically Braced Frames (EBFs) are earthquake-resistant steel structures with excellent shear capacity and ductility. During earthquakes, the EBF link yields first, protecting other structural elements. Traditionally, the link is integrated with the main beam and separated by bracing. However, if the link is damaged, replacing the entire beam becomes necessary. To address this, a vertical link design allows for link replacement without altering the beam section. This study evaluates two vertical link options: a Wide Flange (WF) link section and a Hysteretic Steel Damper (HSD) type Metallic Yielding Damper. Results suggest the WF link is preferable due to superior shear capacity and energy dissipation compared to the HSD link. The findings recommend the WF link for vertical link EBFs to optimize earthquake performance.

Abstract

One of the developments in the world of construction is the variety of structural system configuration types to ensure the strength, stability, efficiency, and safety of buildings. An example of a frequently encountered structural configuration variation is the presence of voids or holes in the floor slab of a building. Floor slabs that have voids affect the structural strength. This study aims to analyze the effect of variations in the size and placement of floor slab voids on the behavior and strength of multi-storey building structures. The results of the analysis are expected to be used as a reference in selecting the size and placement of floor slab voids in building planning. The building structure model analyzed is an 8-storey regular building structure with reinforced concrete materials. The height between floors is 4 meters and the total height of the building is 32 meters. The function of the building is an office located in Semarang City. The earthquake-resistant structural system used is the Special Moment Resisting Frame System (SRPMK). The floor plan size is 18x18 meters with a span between columns of 6 meters. The variations used are 6 void models with different sizes and placements. Each structural model is analyzed using ETABS software. The analysis results state that the larger the void size, the smaller the structural period, the smaller the inter-floor shear force value, and the smaller the inter-floor drift value. The recommendation for selecting the most effective size variations and void placement is in a structural model where the void is placed in the middle of the structure with the largest void size being 6x6 meters.

Abstract

Columns are one of the main structural elements that serve to transfer loads to the foundation. The choice of column material affects the diversity of the structural capacity of multi-story buildings. This study aims to compare steel, reinforced concrete, and composite columns in terms of the behavior and strength of multi-story buildings. This study uses a 7-story building model and a 1-story roof with 3 column model variations, including model 1 steel column, model 2 reinforced concrete column, and model 3 composite column. All three models use steel beams and bondeck floor slabs. The analysis was performed using ETABS v22.0 to compare structural behavior, inter-story shear forces, inter-story deflections, structural safety, and forces in beam and column elements. The results show that the reinforced concrete column model provides the best results for building behavior parameters, including period and translation, as well as internal force values in beams. The steel column model performs best for ground floor shear force parameters. The composite column model performed best in terms of inter-story deflection and internal force values in columns. In addition, no over-stressed structural elements were found in the three models. It was concluded that composite columns had the best structural capacity, combining concrete material that is strong against compression and steel material with high tensile strength to produce a stronger and more efficient structure. Recommendations for further research include using more varied building configurations and reviewing the economic aspects of structural work.
