Simplified procedures are commonly employed to estimate seismic displacements of earth and waste fills. The landmark work of Makdisi and Seed (1978) has been widely adopted in practice. Although this work is widely used, it has a number of significant limitations such as decoupling the sliding block analysis from the seismic response analysis, use of a limited number of recorded earthquake moti...

Reinforced concrete (RC) as a material is most commonly used for buildings construction. Several floor systems are available following the structural and architectural requirements. The current research study provides cost input energy comparisons of RC office different systems. Conventional solid, ribbed, flat plate slab considered in study. Building models three-dimensional using extended ana...

Carbon sequestration by Woody Biomass Burial (WBB) leverages carbon capture through natural photosynthesis, followed the isolation of dead or fallen wood in a relatively shallow Underground Wood Vault (UWV). Long-term geologic containment, including any greenhouse gas decomposition products, depends on careful selection UWV location and depth. To achieve durability 100 y, an initially low-moist...

This paper conducts a detailed review of the seismic hazard, inventory, bridge vulnerability, and bridge retrofit practices in the Central and Southeastern United States CSUS . Based on the analysis of the bridge inventory in the CSUS, it was found that over 12,927 bridges 12.6% are exposed to 7% probability of exceedance PE in 75-year peak ground acceleration PGA of greater than 0.20 g, and ne...

High seismic activity forces Indonesia to mitigate natural disasters minimize the impact of these disasters. One mitigation efforts that can be done is know possibility an earthquake occurring in area. Earthquakes, which are random phenomena, cannot determined with certainty. Therefore, studies seismological statistics used. discusses occurrence earthquakes epidemic-type aftershock sequence (ET...

Sebagai ibu kota Provinsi Sumatera Barat, Kota Padang memiliki risiko tinggi terhadap gempa bumi dan tsunami karena letaknya di antara dua lempeng benua adanya Patahan Semangko. Beberapa tempat perlindungan berfungsi sebagai lokasi evakuasi penyelamatan saat terjadi tsunami. Paper ini menyajikan sebuah sistem pendeteksi yang menggunakan sensor terdistribusi. Identifikasi dilakukan dengan menghi...

Soft storey building is popular due to the functional and aesthetic purpose, despite its weakness in resisting seismic excitation. Nonlinear Static (Pushover) Analysis (POA) is a time saving and simple assessment procedure prosposed in Eurocode 8 (EC8). However, its reliability in designing structure still remains a question. At the first stage, seismic performance of several building models us...

The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...

Impact forces and shock deceleration during jumping and running have been associated with various knee injury etiologies. This study investigates the influence of jump height and knee contact angle on peak ground reaction force and segment axial accelerations. Ground reaction force, segment axial acceleration, and knee angles were measured for 6 male subjects during vertical jumping. A simple s...

Abstract. The Ms 8.0 Wenchuan earthquake in 2008 and 7.0 Lushan 2013 produced thousands of landslides the southern region Longmen Mountains China. We conducted field investigations analyzed remote sensing data to determine distribution law earthquake-triggered landslides. results show a strong negative power relationship between size frequency VII, VIII, IX seismic intensity zones, weak X zone,...
