Study On The Bearing Capacity Of The Inner Skeleton-Thermal Insulation Block Composite Masonry

Masonry structure is refers to the built of brick masonry, stone masonry or blockmasonry structure, is an ancient form of structure. With the rapid development of economyand the expanding of population, the development of the architectural space and the height isput forward. Common sintered clay brick strength especially the tensile strength difficult tomeet the requirements of modern architecture. And the production of clay brick occupies lotsof land, consumes huge amounts of energy, cause serious air pollution. So its dominance isfaced with severe challenges in the field of building materials，concrete block to replace claybricks has become a development trend. The sustained and rapid economic development alsocaused the human demand for energy is strong, but the supply of oil and other fossil fuelenergy face enormous pressure. For our country’s economical society construction savingenergy and improving the efficiency of energy use are urgent. In our country, building energyconsumption accounts for most of the total energy consumption of society, so building energyconservation is imperative，and uniting building structure and energy saving has becomedthe trend of the development of the building next.Within the perspective of "integration of structure energy saving", this thesis putsforward energy-saving bearing heavy block and form a complete set of U type， corner type,1/2type energy-saving bearing heavy block. On this basis, combining with the research resultof encryption of core column composite wall bearing capacity study the team has gained,heavy block-inside insulation tester skeleton composite masonry new train of wall thoughtwas put forward.Based on research methods of the experimental research combining theoretical analysisand numerical simulation, Four key problems including insulation bearing heavy block heat,pressure bearing system can, inner frame composite masonry compression bearing capacityare studied. Research results are:1. For H2type block, the finite element numerical simulation method was used to heattransfer analysis and optimizing the structural style of block. Energy-saving bearing heavyblock and form a complete set of U type, corner type,1/2type were put forward and studied.Tests showed that energy-saving bearing heavy block thickness direction of the heat transfer coefficient is0.527，when the middle hole set core column the heat transfer coefficient is0.628.2. Compressive load and the failure pattern of energy-saving bearing heavy concretehollow block were researched by the static loading test. And contrasting withthe results ofmasonry compressive strength formula adopted by Specification for design of masonrystructures GB50003-2011, introducing the modification coefficient, establishing calculationformula of compressive strength of masonry structure based on the energy-saving frequencyblock masonry test data.3. The basic mechanical properties and the destruction modes of the energy-saving&heavy-bearing concrete hollow block-the inner skeleton composite wall were researched bythe static loading test. The vertical bearing capacity formula for the inner skeleton compositewall was put forward.The above research work aimed at better served for the low-level or multi-layerbuildings in cities and towns, provided the basic test data for the promotion of the wall intowns and villages which embody the low awareness of building energy efficiency, andpromoted the reform of the wall and building energy-saving efficiency.
