Abstract

Nowadays, most of the analyst and designer consider ‘rare’ single earthquake in seismic analysis and design. The repeated earthquakes are ignored even though the actual earthquake event occurs repetitively and the effect of the repeated earthquake is qualitatively acknowledged. Repeated earthquake is the repetition of medium-strong earthquakes at short time interval. The repeated earthquake was reported in many part of the world. This study investigates the effect of this event on the response of the reinforced concrete (RC) buildings. For that purpose, this study uses five generic RC models with different behaviour factor, q (i.e. 1, 1.5, 2, 4 and 6) in which the model with q = 1 is the strongest building and the strength of the building decreases with the increase of the q value. Furthermore, all models are 18-storey to represent high rise buildings in three dimensional in order to consider the effect of earthquake in orthogonal direction. There are 40 repeated near field ground motions which were combined randomly from 20 single near field ground motions employed in this study and 20 residual ground motion records. These repeated earthquakes are divided into two case, i.e. case 2 and case , in which case 2 has two consecutive earthquake(i.e. main shock and aftershock) and case 3 has three consecutive earthquakes (i.e. foreshock, main shock and aftershock). The duration between two consecutive earthquakes is 100s which is enough for the model to cease the motion.  The near field earthquake contains special characteristic which is known as pulse effect that far field earthquake do not has, therefore, this study investigates also the effect of pulse period on the response of the RC buildings. The displacement ductility and storey ductility demand were considered to assess the response of the RC models and they are computed by using  nonlinear time history analysis. It was found that repeated near field earthquake give significant effect to the respond of high-rise RC buildings compared to single near field earthquake.

Abstract

The earthquakes struck a region near the active fault for many times. The yielded structures after an earthquake might become excessive damages after experiencing another earthquake. The concept of seismic design of building has not consider this type of hazard. Recent studies indicate that the effect of repeated earthquake is significantly occurred on the moment resisting bare frames, either made from steel or concrete material. This paper investigates the effect of repeated earthquake on the frames with infilled brick wall. The frames represent school building built on the regions near the Sumatran active fault, Indonesia. The result shows that the sequence of plastic hinges occur on the structures model after experiencing the repeated earthquake. It starts from the brick wall and then spreads to the columns and beams. For the single earthquakes, the brick wall of structures model tends to perform damage, but few of columns and beams experiences hinges. These conclude that the future repeated earthquake can not be underestimated

Abstract

The directivity pulse motion in near-field earthquake affects the responses of structures. The response includes the roof drifts and interstory drifts, which is so-called the ductility demand. Although many studies have done in this topic, the effect of various post-yield stiffness ratio and ductility capacity ratio to the global ductility demands of reinforced concrete (RC) frames under near-field ground motion is not specifically investigated yet. The trend of global ductility demands of RC frames under near-field earthquake is the objective of this study. The frames are modeled with various fundamental period, behavior factor, plastic rotation capacity, post-yield stiffness ratio, and ductility capacity ratio. The study reveals that the effect of ductility capacity ratio on the global ductility demands is apparent as as the plastic rotation capacity changes. The global ductility demand is also found influenced by global post-yield stiffness ratio and behaviour factor.

Abstract

Salah satu hal yang harus dimengerti dalam perencanaan bangunan tahan gempa adalah konfigurasi bangunan dan pengaruhnya terhadap beban gempa. Walaupun denah bangunan yang reguler dan simetri telah diketahui mempunyai perilaku yang baik akibat beban gempa, tetapi pada kenyataannya masih banyak bangunan yang tidak reguler (irreguler) dan tidak simetri tetap dibangun dengan alasan arsitektural. Bangunan yang irreguler menyebabkan distribusi massa, kekakuan dan kekuatannya asimetris sehingga menimbulkan eksentrisitas terhadap pusat massa. Dalam penelitian ini dilakukan simulasi terhadap bangunan asimetris yang diberikan beban gempa yang disertai pulse. Tujuan penelitian ini untuk melihat besarnya simpangan dan rotasi lantai yang terjadi pada bangunan yang asimetris terhadap kekakuan. Setelah dilakukan penelitian, didapatkan hasil adanya perbedaan hasil simpangan yang terjadi akibat gempa disertai pulse dan tanpa pulse. Perbedaannya mencapai 8% hingga 20%. Rotasi yang terjadi pada bagian bangunan yang memiliki inersia yang lebih besar (sisi kaku) lebih kecil dari pada bagian bangunan yang memiliki inersia yang lebih kecil (sisi fleksibel). Adanya perbedaan eksentrisitas kekakuan pada sistem bangunan juga mempengaruhi rotasi lantai inelastis.

Abstract

Gempa bumi merupakan suatu fenomena alam yang tidak dapat dielakkan oleh manusia yang mana kejadian itu mengakibatkan kerugian material dan korban jiwa.Akibat yang ditimbulkan tersebut kebanyakan terjadi oleh kerusakan dan runtuhnya suatu bangunan.Teknologi yang dikembangkan pada pondasi belakangan ini sangat berpengaruh untuk meminimalisir keruntuhan suatu struktur bangunan akibat gempa bumi.Isolasi Dasar merupakan terobosan teknologi yang mutakhir yang diletakkan pada pondasi yang berfungsi mengurangi efek dari gempa bumi.Kekakuan pada struktur juga mempengaruhi ketahanan bangunan dari kerusakan dan keruntuhan.Dinding bata berfungsi meningkatkan kekakuan suatu stuktur bangunan.Tugas akhir ini bertujuan untuk mengetahui dan membandingkan respon struktur bangunan yang menggunakan teknologi isolasi dasar dan fixed base. Parameter yang ditinjau yaitu periode alami (T), gaya geser (V), dan simpangan (δ). Analisis yang dipakai adalah analisis statik ekivalen dan analisis respon spektrum. Terdapat 4 model yang menjadi bahan perbandingan, yaitu struktur bangunan fixed base tanpa dinding bata, fixed base dengan dinding bata, isolasi dasar tanpa dinding bata, dan isolasi dasar dengan dinding bata.

Abstract

This paper investigates the response of inelastic moment resisting concrete building under repeated earthquakes. 2D models consist of 3-storey, 6-storey and 9-storey representing low to medium rise building frame were designed using seismic load and ductility class medium (DCM) according to the requirements set by Euro Code 8. Behaviour factor and stiffness degradation were also taken into consideration. Seven sets of real repeated earthquakes as opposed to artificial earthquakes data were used. The response of the frame was measured in terms of the inter-storey drift and maximum displacement. By adopting repeated earthquake, the recorded mean IDR increased in the range of 3% - 21%. Similarly, in the case of maximum displacement, the values also increased from 20 mm to 40 mm. The findings concluded that the effect of using repeated earthquake in seismic analysis considerably influenced the inter-storey drift and the maximum displacement.
