Careful design of public buildings is needed to provide an optimized response that accounts for various loading cases, such as seismic, wind, and blast loads. Effective building design needs to be well-balanced for various scenarios. Fundamental understanding of structural behavior and dynamic response is crucial for the protective building design under blast load, in which peak pressure is orders of the highest magnitude, but their durations are very short. This study incorporated the explicit dynamics method into the investigation, mainly focusing on simulating fundamental components' struct Authors: Wisit ,,Kawayapanik;Khanathip ,,Prabuntrarik;Pornpen ,,Limpaninlachat;Yasothorn ,,Sapsathiarn;Panon,, Latcharote.

Enhancing Structural Assessment: An Integrated Approach Using 3D Applied Element Method and Sensitivity-Based Model Updating

Effective vulnerability assessment requires an understanding of and ability to forecast the behaviour of buildings, particularly in earthquake-prone areas. Existing building modelling and analysis are made possible by the 3D Applied Element Method (AEM), although the accuracy of the method is greatly dependent on the caliber of the input data. This study examines the improvement of creating models utilizing a sensitivity-based model update method built inside the 3D AEM framework. Our method's key component is the capacity to obtain precise information on a building's materials, particularly i Authors: Chaitanya Krishna,,Gadagamma. Presented at TSER2023.

A 1D velocity model of northern Thailand: Preliminary results

The earthquakes in Thailand and adjacent areas have been monitored by earthquake observation division, Thai Meteorological Department (TMD). The earthquake location was calculated by using a global velocity model IASP91 (Kennett and Engdahl, 1991). The earthquake location mainly depends on the accuracy of predicted travel-times and crust and mantle velocity structure (Flanagan et al., 2007). Therefore, an appropriate regional velocity model was required to improve the earthquake location accuracy. This study aims to develop 1D velocity model used for local epicenter location calculation.

Seismic retrofit of RC frame with expanded metal

Generally, the damage of the commercial building during an earthquake was due to soft story failure of the ground floor columns because the ground floor columns are more slender and higher than the upper floors. This paper presents the retrofit of the reinforced concrete frame using expanded metal. The rigid frame specimen was chosen from the typical 3-story commercial building. Two specimens included the controlled rigid frame and the strengthened frame using expanded metal sheet. The specimens were subjected to lateral load up to failure. It was found that the effect of strengthening enhance Authors: Phaiboon,,Panyakapo. Presented at TSER2023.

Liquefaction Vulnerability Assessment in Low-Seismic Regions: A Chiang Rai, Thailand Case Study

The liquefaction concerns of the foundation ground in urban zones of Chiang Rai arises from a prior instance of liquefaction occurring in remote northern Thailand in 2011. Most areas are underlain by clayey sand deposits from paleochannels, which are highly susceptible to liquefaction. Therefore, this study aims to raise awareness regarding the risk of liquefaction in densely populated areas of Chiang Rai. To evaluate the likelihood of liquefaction, this research conducted Standard Penetration Tests on newly-installed boreholes and assessed the liquefaction potential through a simplified proce Authors: Pakawadee ,,Anussornrajkit;Weeradetch,,Tanapalungkorn;Suched,,Likitlersuang.

Rapid structural identification of existing buildings subject to earthquake ground motion: The case study of Chiang Mai and Chiang Rai

In the current research project, three work packages have been adopted. Firstly, ambient vibration measurements have been performed in a number of buildings in order to obtain the building's dynamic properties. Secondly, Finite Element Models have been created in order to check the inelastic properties of selected buildings for different earthquake hazard levels. Finally, a long-term structural health monitoring system using low-cost sensors will be adopted in order to monitor and validate the response of critical infrastructure as well as inform local staff and building occupants of earthquak Authors: Pennung,,Warnitchai;Nakhorn,,Poovarodom;Teraphan,,Ornthammarath.
