Abstract
In order to solve the problems of complex construction, poor weather resistance, and environmental pollution of conventional thermal insulation materials, this paper introduces a new type of insulation decorative block (IDB) filled with insulation materials. Different anchoring methods were adopted to study the influence of anchor bolts on the out-of-plane mechanical properties of IDB walls. The test results revealed that the anchor bolts could effectively prevent the appearance and development of cracks in the specimens. With the increase of anchor bolts, the acceleration and displacement of the IDB walls decreased. Compared to rectangular arrangement, the staggered pattern of anchor bolts could reduce the relative displacement and acceleration. The structural calculation of IDB walls was carried out to determine the number of anchor bolts at different heights, and design suggestions were given to improve the performance of IDB walls. The analysis and test results indicated that the IDB is suitable for application in engineering structures.
Highlights
Nowadays, one of the problems that must be solved is how to reduce the emissions by reducing the amount of energy consumed in economic development
It could be concluded that the crack usually appeared firstly at the bottom of the insulation decorative block (IDB) wall, and as the PGA increased, cracks began to appear in the top corner of the specimen. e cracks mainly appeared at the joint of the IDB wall, ground beam, and shear wall, and there were basically no cracks in the interior of the IDB wall
Frequencies, acceleration, and displacement are evaluated, and the performance of anchorage mode is examined. e calculation formula of the number of anchor bolts and design suggestions are given based on the experimental phenomena, so as to promote the application of IDB in engineering. e results obtained from the tests are briefly summarized as below: (1) Appearance and development of cracks between the IDB wall and shear wall are obviously affected by the number of the anchor bolts. e larger the number of anchor bolts, the smaller the seismic load at the time of crack appearance, the shorter the crack length, and the smaller the crack width
Summary
One of the problems that must be solved is how to reduce the emissions by reducing the amount of energy consumed in economic development. E engineering application of XPS and EPS, as organic materials, is affected by the moisture content and high temperature: (1) the heat transfer coefficient increases with the increase of water content [3,4,5]; (2) the flammability of materials threatens the safety of structures [6,7,8]. Ese conventional insulation materials could be used as additives in composite materials [9,10,11,12] or directly used as external thermal insulation materials of the buildings When these insulation materials are directly used as building envelope components, structural measures and moisture control components should be proposed to improve the waterproof and fireproof properties of the materials during the construction process [13,14,15], which increases the construction cost and construction period. In order to deal with the defects of these conventional insulation materials in engineering application, the research on the building insulation materials should be strengthened.
