Hysteresis Analysis of Prestressed Brick Frame with Strawbale Masonry Infill Subjected to Seismic Loads

Abstract

:This study looks at designing and evaluating strength of typha strawbale wall cross section rather than the assumption of edge column acting as axially loaded members that should resist all vertical members from the loads acting on the wall. Based on the aforementioned claim, the objective of this work is to provide the average design thickness for the cement-plastered typha strawbale that stiffens the prestressed brick frame. Data on strength and deformation of the structure are the input for the analytical models. Pseudo-dynamic earthquake response tests, of a one quarter (¼) scale model low rise storeys prestressed brick frames stiffened with cement plastered strawbale masonry was conducted. The structure is idealized as plane frames. The analysis utilised the hysteresis models for members' models as timeindependent. The force-displacement relationship of the members' models has been evaluated by the approximate method on the basis of the material properties and structural geometry. A model was investigated with straw bale infill panel to determine the hysteretic parameters, stiffness deterioration and strength degradation due to seismic forces.

Análisis de la perspectiva del usuario con respecto a los edificios con fardos de paja: Un estudio de encuesta

“…In this sense, the possible use of agricultural waste and other biological materials as construction materials has gained attention from researchers, builders, and customers (6). One material that meets with these requirements is straw bale (3), whose application is cheap, readily available, ensure high thermal comfort, and gives flexibility in terms of workability and strength, providing buildings with cleaner, sustainable and responsible production (7)(8)(9)(10). In this context, this research seeks to demystify the idea that strawbale buildings, which for decades inhabited the subconscious of children around the world as a kind of fragile building due to the story of the Three Little Pigs, is actually a solid and trustable construction technique, with a high degree of acceptance from its users.…”
