Evaluasi Struktur Bangunan Pasar Inpress Blok IV Gedung B dengan Metode Pushover

Inpres market block IV Pasar Raya Padang is not designed as a shelter building, but is designated as a vertical evacuation site when a tsunami occurs. This study aims to evaluate the structural performance of Inpress market block IV zone B. The method used for this research is the pushover analysis method. According to FEMA P-646/2019, vertical evacuation refuge structures are included in tsunami risk category IV, based on the risk category the maximum performance level is at the Immediate Occupancy (IO). For loads on buildings, refer to SNI 1727:2020 and SNI 1726:2019 for earthquake loads. For the calculation of the capacity of concrete structural elements, refer to SNI 2847:2019. Structural analysis was carried out using the SAP2000 version 16. After analysis, based on performance points, drift ratio that occur due to earthquake loading in X-direction and Y-direction are 0,05875% and 0,0067%. The maximum total drift that occurs is smaller than that required by ATC-40 for the Immediate Occupancy performance level, which is 1%. Thus, the structure performance level is Immediate Occupancy. This means that the Inpress market block IV building is still strong enough against earthquake loads.

A Study on the Analysis of Vertical Walking Speed Considering the Confluence of Occupants in the Stairwell of a High-rise Building

In a fire incident case in a modern high-rise complex building, most occupants use the stairs to evacuate; hence, it is critical to secure the safety of vertical escape routes, such as the stairs. However, in Korea, the size of the stairwell is stipulated as a universal standard, and there are insufficient regulations and studies on the behavioral characteristics of occupants that may occur during the vertical evacuation of buildings. Therefore, in the evacuation experiment conducted at the W University in Japan, the relationship between the density and velocity of the occupants and the flow coefficient were analyzed during merging in the stairwell to derive a regression equation. When the stair width acted as a variable, the behavioral characteristics of the occupants and the evacuation time inside the stairwell were analyzed to obtain the basic data for improving the evacuation safety in the stairwell.

Simulating a Vertical Evacuation of a NICU and PICU to Examine the Relationship Between Training and Preparedness

Objective: The aim of this study was to implement pediatric vertical evacuation disaster training and evaluate its effectiveness by using a full-scale exercise to compare outcomes in trained and untrained participants. Methods: Various clinical and nonclinical staff in a tertiary care university hospital received pediatric vertical evacuation training sessions over a 6-wk period. The training consisted of disaster and evacuation didactics, hands-on training in use of evacuation equipment, and implementation of an evacuation toolkit. An unannounced full-scale simulated vertical evacuation of neonatal intensive care unit (NICU) and pediatric intensive care unit (PICU) patients was used to evaluate the effectiveness of the training. Drill participants completed a validated evaluation tool. Pearson chi-squared testing was used to analyze the data. Results: Eighty-four evaluations were received from drill participants. Forty-three (51%) of the drill participants received training and 41 (49%) did not. Staff who received pediatric evacuation training were more likely to feel prepared compared with staff who did not (odds ratio, 4.05; confidence interval: 1.05-15.62). Conclusions: There was a statistically significant increase in perceived preparedness among those who received training. Recently trained pediatric practitioners were able to achieve exercise objectives on par with the regularly trained emergency department staff. Pediatric disaster preparedness training may mitigate the risks associated with caring for children during disasters.

Analisis Kelayakan Proses Evakuasi Vertikal pada Daerah Zona Merah di Kecamatan Kuta Alam

Kuta Alam Subdistrict is one of the Districts which are prone to tsunami disaster, 5 Gampongs from 11 Gampongs in Kuta Alam Sub-district are Gampong in the red zone, namely Gampong Lampulo, Gampong Lamdingin, gampong Lambaro Skep, Gampong Mulia, and gampong Peunayong. Based on the level of vulnerability, the five Gampongs are included in the Village which has a very high risk of tsunami. The main strategy to reduce disaster risk is to reduce casualties, namely by evacuating residents in vulnerable areas before the tsunami wave arrives in the area. Vertical evacuation is an evacuation carried out by moving residents from exposed areas by utilizing tall buildings or hills around vulnerable areas as evacuation sites. The feasibility of evacuation can be seen from the feasibility of the route, the feasibility of alternative evacuation buildings, travel time, and the mode used. From the analysis, it was found there is 11 alternative evacuation buildings can be used as evacuation buildings, where all buildings are declared feasible, and 11 evacuation routes, where only 1 route is declared feasible to be taken by vertical evacuation, while the other 10 routes are not feasible to walk
