"Bangunan studi kasus gudang terdiri dari 3 lantai dengan bentang tipikal 11.4 m (kecuali pada bagian driveway terdapat bentang 17.1 m) dan tinggi antar lantai 11.2 m. Struktur menggunakan beton fc’ 40 MPa dan tulangan baja BjTS 420B. Struktur ini menanggung beban hidup gudang sebesar 25 kN/m2, beban hidup driveway 15 kN/m2, dan atap datar 1 kN/m2. Sementara itu, beban gempa yang diberikan adalah gempa respons spektrum. Bangunan ini berlokasi di Depok dengan kelas situs tanah lunak sehingga termasuk kategori desain seismik D dan memiliki sistem pemikul gaya seismik berupa sistem rangka pemikul momen khusus (SRPMK). Desain struktur bangunan dilakukan dengan dua skema, yaitu struktur Konvensional di mana digunakan pelat dua arah yang menumpu balok sebagai media transfer beban ke kolom dan struktur post-tensioned flat slab (PTFS) di mana digunakan pelat dua arah prategang yang secara langsung menumpu kolom dengan penebalan berupa drop panel. Pada struktur PTFS dilakukan pemisahan sistem penahan gaya gravitasi dan lateral (SGLR). Kolom penahan beban gravitasi saja akan dicek menggunakan prinsip kompatibilitas perpindahan. Struktur PTFS memiliki periode getar, berat seismik, gaya geser dasar, dan maximal story displacement lebih besar dibandingkan struktur konvensional. Volume tulangan (35.355%), beton (1.421%), dan bekisting (26.683%) struktur PTFS lebih kecil dibanding struktur konvensional dengan terdapat penambahan volume untuk strand (100%). Perbedaan biaya terbesar terdapat pada komponen balok, di mana penggunaan post-tensioned flat slab mampu menghemat biaya sebesar 62.712%. Total penghematan yang terjadi adalah sebesar 9.161%.

The warehouse case study building consists of 3 floors with a typical span of 11.4 m (except for the driveway section where the span is 17.1 m) and a height between floors of 11.2 m. The structure uses fc' 40 MPa concrete and BjTS 420B steel reinforcement. This structure supports a warehouse live load of 25 kN/m2, a driveway live load of 15 kN/m2, and a flat roof load of 1 kN/m2. The given earthquake load is response spectrum earthquake. This building is located in Depok with a soft soil site class so it is classified as seismic design category D and has a seismic force resisting system in the form of a special moment resisting frame system (SMRFS). The building structure design is carried out using two schemes, namely a Conventional structure where a two-way slab supported by beam as a load transfer medium to the column is used and a post-tensioned flat slab (PTFS) structure where a two-way prestressed slab that directly supported by column with thickening. in the form of a drop panel is used. In the PTFS structure, there is a separated gravity and lateral resisting system (SGLR). Gravity-load-only columns will be checked using the principle of displacement compatibility. PTFS structure has a vibration period, seismic weight, base shear force, and maximum story displacement greater than conventional structure. The volume of reinforcement (35.355%), concrete (1.421%), and formwork (26.683%) for PTFS structure is smaller than conventional structures with strands volume (100%) added in the PTFS structure. The biggest cost difference is in the beam components, where the use of post-tensioned flat slabs can save costs of 62.712%. The total savings that occur are 9.161%."

A green building with proper maintenance will have higher energy efficiency and longer lifetime, as damages to building utilities can be minimised. One of the vital utilities are electrical components. Damages to electrical components may have fatal consequences such as short circuit or fire. This research aims to improve the maintenance of electrical components of green building. A case study is taken from a government green building for electrical components, in order to meet the building reliability requirements which consist of safety, health, comfort, and convenience. Maintenance system which is Work Breakdown Structure (WBS) of green building maintenance integrated with information systems and Building Information Modeling (BIM) are influential factors for building maintenance performance.

"Dengan adanya perubahan peraturan SNI 1726 “Standar perencanaan ketahanan gempa untuk struktur bangunan Gedung”, maka bangunan yang lama akan mengalami penambahan beban gempa. Untuk mengembalikan beban gempa ke nilai awal dapat dilakukan dengan menggunakan isolator. Untuk penelitian ini isolator yang digunakan ialah lead rubber bearing dan ditempatkan pada lantai paling atas bangunan lalu menambah beban diatas lead rubber bearing. Objek pada penelitian ini ialah bangunan dengan denah berbentuk L yang akan divariasikan sebanyak 10 model berisolator dan 1 model fix-based. Hasil dari penelitian ini akan menganalisa pengaruh variasi beban dan kekakuan lead rubber bearing terhadap respons struktur bangunan, Analisa yang digunakan ialah Analisa respons spektrum dengan parameter yang dibandingkan meliputi: periode getar, gaya geser tingkat, simpangan antar lantai dan pusat massa. Berdasarkan hasil penelitian menggunakan analisa respon spektrum, penggunaan lead rubber bearing dapat mengurangi gaya geser dasar akibat gempa berkisar antara 19-23

With the amendment of SNI 1726 regulation "Standards for planning earthquake resistance for building structures", old buildings will experience additional earthquake loads. In order to restore the earthquake load to the initial value, it can be done using an isolator.The isolator that is used for this study is lead rubber bearing, and it is placed on the top floor of the building and then added an additional load at the top of lead rubber bearing. The object of this study is a building with an L-shaped plan with variation of 10 isolated models and 1 fix based model. The results of this study will analyze the structural response of buildings caused by variations in load and stiffness of lead rubber bearing on. The analysis used in this study was responses spectrum analysis with parameters that being compared covers: period of vibration, story shear, intersection between floor and center of mass. Based on the results of the study using response spectrum analysis, the use of lead rubber bearings can reduce the base shear due to earthquakes ranging from 19-23%."

"Traditionally, engineers have used laboratory testing to investigate the behavior of metal structures and systems. These numerical models must be carefully developed, calibrated and validated against the available physical test results. They are commonly complex and very expensive. From concept to assembly, Finite element analysis and design of metal structures provides civil and structural engineers with the concepts and procedures needed to build accurate numerical models without using expensive laboratory testing methods.
