Design of Compressed Stabilized Earth Bricks (CSEB) for Earthquake Resisting Building in Nepal

Abstract

This study focussed on determining values for characteristics utilised in current design calculations, such as Young's modulus, density, compressive and tensile strength, and the first natural period of a CSEB building, by in-field testing. Finding a reliable numerical model of a CSEB building was another goal of this work. A CSEB building's dynamic reaction to an impulse was evaluated in the field. This test was accomplished to calibrate the mass and stiffness distribution of the model and validate the numerical model. The results of a review of the literature on the subject of earthquake design for masonry and CSEB structures led to the development of design recommendations for the CSEB buildings constructed by Build over Nepal. Three inquiries vis-à-vis design deviations that arise from observations made during the CSEB building's construction were also addressed. The young’s modulus test density analysis and compression strength test and tensile strength test were performed on the CSEB material and found the positive results. It is observed that manufacturing of blocks are reliant on on the manufacturing process and not depends on the curing of the blocks. Compressive and tensile strength would be increased after the curing process it was 11.8 MPa (tensile strength) and 1.81 MPa (compression strength).
