Abstract

Gempa Aceh tanggal 26 Desember 2004 telah mengubah paradigma dalam penanganan bencana di Indonesia, khususnya akibat aktivitas seismik dan bencana ikutannya seperti tsunami, tanah longsor, banjir bandang dan likuifaksi, dan mendorong Kementerian Pekerjaan Umum untuk melakukan revisi terhadap Peta Gempa 2002 dan berinisiatif menginisiasi penyusunannya dengan menghimpun para ahli di bidang gempa bumi. Hasil studi dari  tim ahli tersebut kemudian dituangkan dalam bentuk Peta Zonasi Gempa 2010 dan telah menempatkan posisi kota Palu khususnya dan wilayah Sulawesi Tengah umumnya ke dalam wilayah yang berpotensi terlanda gempa dengan magnitude maksimum 7,9 SR (skala Richter). Ini berarti, seluruh komponen masyarakat di wilayah Sulawesi Tengah wajib bersiap diri dalam menghadapi bencana yang datangnya sulit untuk diprediksi dengan melakukan usaha mitigasi bencana yang salah satunya adalah dengan melakukan evaluasi secara cepat (Rapid Visual Screening) terhadap seluruh bangunan yang ada untuk menilai kerentanannya terhadap gempa bumi

Abstract

Palu City is located in an earthquake-prone area. To Construct a building in earthquake-prone areas, many people like to construct buildings far away from the epicenter, we should be able to construct buildings in earthquake-prone areas without any worries about the resilience of the building related to seismic load. In this final project, a 4 (four) storey shophouse will be designed as the Special Moment Resisting Frame method using the SNI-2847-2019 and SNI- 1726-2019 standard. The seismic load was simulated using the response spectrum and the structural element was analyzed by 3D Structural Analysis Programme.

Abstract

Columns are one of the structural elements that greatly influence the behaviour of the structure. Columns are capable of holding axial compression loads and transmitting them to the structural elements below. Column capacity can be increased by the confinement of lateral reinforcement/stirrup. The stirrups function to maintain the compressive strength capacity of the concrete column before and after spalling. Advances in software technology have had a very significant impact on the development of structural element analysis methods, including software based on the Finite Element Method (FEM), Abaqus/CAE Student Edition. It can also simplify several laboratory research of Civil Engineering into a simulation. However, in simulation practice, parameters in the form of material data are needed as input. To get the same behaviour between the test object and the simulation, convergent parameters are needed. The parameters to be analyzed are CDP (Concrete Damage Plasticity) plastic parameters. While the simulation for loading, shape of the test object, and placement refers to the results of previous studies. The reinforced concrete column test model used consists of 5 (five) different variations of stirrups. The results of the simulation show that reinforced concrete columns with stirrups provide support in the form of shear force capacity that can maintain the value of the axial compressive strength capacity. From the five existing test models, it was obtained that the increase in the value of the axial compressive strength capacity of the column due to the variation of stirrups for column B, column C, column D, and column E to column A (without stirrups) were 115%, 120%, 121%, and 119% consecutively. The output values from the analysis include the diagrams of axial force and displacement, column interaction diagrams, and material stress-strain diagrams

Abstract

After the 2018 earthquake, a number of constructions in Palu City, especially buildings, grew rapidly. In the construction of buildings using steel structures, the use of braces aims to reduce displacement and increase the capacity of shear forces to resist cracking. Steel produces greater ductility when compared to other structural materials, so it is a major requirement in designing earthquake-resistant steel structures. In this study, the structure of the building was designed to be 3 (three) stories in educational purpose. The structural system has a dual system combination Special Moment Resisting Steel Frame System (SMRF) and a lateral force resisting system, namely a Special Concentric Brace Frame System (SCBF). Steel material used are BJ 41 quality (fy = 250 MPa; fu = 410 MPa) and concrete using quality f'c = 25 MPa. The loads acting on the structure are dead load, live load, wind load, rain load, and earthquake load. The results of the structural analysis are: 99,42% mass participation is obtained for the x direction in mode 4 and 98,97% for the y direction in mode 5, the SRSS method was used to combine the number of mode varieties used, the obtained dynamic earthquake shear force response spectrum (x direction = 281993,31 kg and y direction = 280187,36 kg) has exceeded the equivalent static earthquake shear force (x direction and y direction = 280096,09 kg), the displacement that occurs in the x direction and y direction does not exceed the allowable displacement of 34,615 mm, the stability coefficient obtained in the x-direction and y-direction does not exceed the P-Delta effect limit of 0,1 and the structural stability limit of 0,0909, the structure does not occur horizontal irregularities and vertical irregularities, the Special Moment Resisting Steel Frame System (SMRF) has exceeded the percentage of 25% (x direction = 62,49% and y direction = 58,26%), the structural performance level in the x direction and y direction is in Damage Control condition.
