Structure analysis of building functions transition on the earthquake area five reviewed from costs and time schedule

The purpose of this study is to determine the dimensions and reinforcement of structure, cost, and schedule due to the transition structure of the building function. The structural transition of building functions is carried out in the earthquake area five with the classification of soft and hard soils. The building used as a research model is a 3-story residence on Nuansa Utama Selatan Street number 3, Jimbaran, Bali. The planning of this building will be converted into office buildings and shophouse on the 2nd and 3rd floors functioning as a warehouse in the earthquake area five in Bali with the classification of soft and hard soil that will be analyzed using SAP 2000 program so that the structural dimensions are used as a reference in the creation of costs, and schedule obtained using Microsoft Project program. The analysis of structure shows that the structure of a residential house on hard soil has the dimensions and reinforcement of the smallest structure. The ratio of structural reinforcement in the transition of structure functions from residential house to office on hard soil by 1.32% with the lowest structure cost ratio by 1.80% and schedule of the structure by 3.80%.

Discovering Vegetation Recovery and Landslide Activities in the Wenchuan Earthquake Area with Landsat Imagery

Post-seismic vegetation recovery is critical to local ecosystem recovery and slope stability, especially in the Wenchuan earthquake area where tens of thousands of landslides were triggered. This study executed a decadal monitoring of post-seismic landslide activities all over the region by investigating landslide vegetation recovery rate (VRR) with Landsat images and a (nearly) complete landslide inventory. Thirty thousand landslides that were larger than nine pixels were chosen for VRR analysis, to reduce the influence of mixed pixels and support detailed investigation within landslides. The study indicates that about 60% of landslide vegetation gets close to the pre-earthquake level in ten years and is expected to recover to the pre-earthquake level within 20 years. The vegetation recovery is significantly influenced by topographic factors, especially elevation and slope, while it is barely related to the distance to epicenter, fault ruptures, and rivers. This study checked and improved the knowledge of vegetation recovery and landslide stability in the area, based on a detailed investigation.

Valuable Clues for DCNN-Based Landslide Detection from a Comparative Assessment in the Wenchuan Earthquake Area

Landslide inventories could provide fundamental data for analyzing the causative factors and deformation mechanisms of landslide events. Considering that it is still hard to detect landslides automatically from remote sensing images, endeavors have been carried out to explore the potential of DCNNs on landslide detection, and obtained better performance than shallow machine learning methods. However, there is often confusion as to which structure, layer number, and sample size are better for a project. To fill this gap, this study conducted a comparative test on typical models for landside detection in the Wenchuan earthquake area, where about 200,000 secondary landslides were available. Multiple structures and layer numbers, including VGG16, VGG19, ResNet50, ResNet101, DenseNet120, DenseNet201, UNet−, UNet+, and ResUNet were investigated with different sample numbers (100, 1000, and 10,000). Results indicate that VGG models have the highest precision (about 0.9) but the lowest recall (below 0.76); ResNet models display the lowest precision (below 0.86) and a high recall (about 0.85); DenseNet models obtain moderate precision (below 0.88) and recall (about 0.8); while UNet+ also achieves moderate precision (0.8) and recall (0.84). Generally, a larger sample set can lead to better performance for VGG, ResNet, and DenseNet, and deeper layers could improve the detection results for ResNet and DenseNet. This study provides valuable clues for designing models’ type, layers, and sample set, based on tests with a large number of samples.

Seismic Effects on Different Structural Members

Civil engineers deal with constructing differing types of structures with guaranteeing safety, sturdiness and utility. Currently days “earthquake “is a natural tragedy that affects the structures with their safety and utility. The quantity of harm that earthquake will cause to structures is rely upon sort of building, sort of soil, Technology used for earthquake resistance, and last however not the smallest amount Location of building. Effects of earthquake area unit mostly counting on sort of soil within which foundation of building is finished as a result of earthquake changes the motion of ground that results the failure foundation. Therefore it's vital to check the behavior of various soils at the time of construction of structures. Earthquake will be resisted by varied technologies utilized in building, one amongst these area unit shear wall. It improves the structural performance of building subjected to lateral forces because of earthquake excitation. Much analysis comes area unit afoot worldwide for development of effective ways for estimating unstable demands for performance-based engineering of buildings.

Aandacht voor zingeving : Context en praktijk van geestelijke verzorging in het aardbevingsgebied van Groningen

Attention for Meaning-Making Processes: Context and Practice of Spiritual Care in the Earthquake Area of GroningenIn the North of the Netherlands spiritual caregivers have been employed to respond to the social and personal needs resulting from human induced earthquakes. In the Netherlands knowledge on spiritual care in times of disasters is limited. Central to the present study are two questions: How is spiritual care being put into practice in Groningen? And how do the spiritual caregivers cooperate with others in psychosocial care and in the social domain? This article describes the context, the reasons spiritual care came to be provided and the primary activities of the spiritual caregivers during their initial year of practice.
