Abstract—This paper presents a numerical investigation on the seismic performance of a benchmark bridge with different optimal isolation systems under near fault ground motion. Usually, very large displacements make seismic isolation an unfeasible solution due to boundary conditions, especially in case of existing bridges or high risk seismic regions. Hence, near-fault ground motions are most l...

Offshore jacket-type towers are steel structures designed and constructed in marine environments for various purposes such as oil exploration and exploitation units, oceanographic research, and undersea testing. In this paper a newly developed meta-heuristic algorithm, namely Cyclical Parthenogenesis Algorithm (CPA), is utilized for sizing optimization of a jacket-type offshore structure. The a...

The December 2004 earthquake and tsunami in Aceh still have an impact on buildings. Korem 012/TU Mess Building Ujong Karang Meulaboh, Province is one of the buildings affected. Structural strengthening required by comparing strength existing building with planned building. structural method used this research concrete jacketing construction method. This study aims to evaluate compare how much c...

The search for methods that provide savings greatly drives the alternatives when it comes to cost reduction. obsession with aesthetics and cheaper civil construction, can lead unexpected dangerous results. reduction of dimensions columns be done consciously, always keeping in mind compliance normative standards combined structural optimization. objective this work was evaluate efforts resulting...

Dalam pekerjaan konstruksi, perubahan desain awal sampai akhir pembangunan akan selalu terjadi desain. Perubahan dapat akibat gaya-gaya karena fungsi lantai oleh permintaan pemilik (owner) atau kondisi dinilai pihak pelaksana untuk dilakukan efisiensi dan percepatan kecepatan pelaksanaan pekerjaan. Pada skripsi ini menyampaikan alternatif kolom utama menggunakan beton mengalami kendala sehubung...

The effect of wind and earthquake on the structures can be specified briefly by horizontal forces act varied in its value direction depending location distance from sea case load seismic activity region an earthquake. These conflict concept with structural stability structure. Most designer engineers adopted vertical only design calculations neglecting based opinion that are not effective. This...

The housing typologies that meet shelter and other basic needs are diverse, bungalows one of them. These buildings generally single-story mostly use wooden building materials. This paper introduces a new construction technique using steel, which is more durable than typical bungalow houses. design aimed to create stock based on the logic mass production, where modular steel bars can be prefabri...
