Description
Technical field
The present invention relates to a kind of calculation methods of the shearing strength of masonry structure component under consideration different water cut, specifically relate to
And a kind of calculation method of the shearing strength of the masonry structure component after floods.
Background technique
China is the country of a multiple earthquake, and due to level of economic development etc., the existing masonry in part
Structure is all without carrying out necessary Aseismic Design, and shock resistance is almost without consideration, masonry structure shearing resistance itself, bending resistance, tension
Intensity is significantly relatively low, and anti-seismic performance is poor.The Wenchuan special violent earthquake that on May 12nd, 2008 occurs causes local building
Very big destruction, other than earthquake grade and the rare for many years reason of earthquake intensity, most of shock resistance of the building differences are even more
One important reason.
In last century China's vast rural area self-built housing, the objective feelings such as gather materials on the spot of construction cost and construction material are considered
Condition, generallys use clay common brick and the greyish white mortar of clay is built, and structural system is simple, some even owe reasonable.This point Soviet Union
Southern area is particularly acute, and is embodied as building using 85 clay bricks and the greyish white mortar sky bucket of clay.Secondly, China is being just at this stage
Urbanization Construction is being carried out, us are more needed to masonry structure to the earthquake-resistant building Testing and appraisal in the old shanty town in city,
Especially low laying areas is more particularly important by the shock resistance identification and early warning of the old masonry structure building after floods.
A large amount of brick masonry housings cause the deterioration of material property and shear resistant capacity to reduce due to the immersion of flood,
Even collapse.Existing national regulation is not directed to the method that anti-seismic detection is identified after brick masonry structure water impregnates.Floods with
The Testing and appraisal method of Hollow Block Masonry Structure Anti-seismic afterwards is that vast Testing and appraisal and seismic hardening colleague technology urgently to be resolved are difficult
Topic.
Summary of the invention
In order to overcome defect present in background technique, the technical solution adopted by the present invention to solve the technical problems is:
The calculation method of the shearing strength of masonry structure component, the steps include: under a kind of different water cut
First step builds the investigation of local environment position:
Building local environment position refer to environment position locating for house whether be positioned at floodplain, flood storage and detention and the area Yi Hong Yi Lao,
And the dangerous library of disease, silt arrester, barrier lake, reservoir, tailing dam or the storage downstream Hui Ku, if suffer from floods；
Second step, the investigation of masonry structure building system:
Masonry structure building body means that the type for bearing the specific component of upper load effect is different, and power transmission route is different and distinguishes
For mixed structure, brick mix structure or post and panel structure；
Third step: the determination of masonry structure type
It chooses and uses 85 bricks or 95 brick masonries, masonry mortar is the masonry structure that M5.0 mixed mortar is prepared into；
Four steps: the shearing strength detection of masonry structure
The detection of brick setting shearing strength can be double according to the simple shear method in situ in " masonry project onthe technology of site test standard ", original position
It cuts method or " drill core test shear strength of masonry and masonry mortar intensity technique regulation " is measured；
5th step: the detection of masonry moisture content
On-site test is carried out using moisture content of the microwave tomography method to brick setting, obtains relative moisture content；It uses at the scene
Dry follow the example of is sampled brick setting, obtains absolute drift using weighting method after dried in laboratory, carries out masonry moisture content
Calibration amendment；
6th step: being fitted the shear strength calculation formula of masonry, carries out the review of earthquake-resistant structure bearing capacity
In the real process for doing Testing and appraisal to existing brick masonry structure building, shearing strength is built to identification brick masonry structure
It is detected, first layouts and test out wall moisture content with microwave detector, obtain following fitting formula；
fv,m =k5
In formula: fv,m: shear strength of masonry average value (N/mm2)；
f2: the mean compressive strength (N/mm of mortar2).
Wherein, masonry construction k is not impregnated5It is 0.187；Impregnate 2 days masonry construction k5It is 0.27；Impregnate 7 days masonry construction k5
It is 0.19；Impregnate 30 days masonry construction k5It is 0.182.
7th step: shear strength of masonry applicating evaluating
On the basis of analyze to the data information investigating, reconnoitre, detect comprehensively, according to all kinds of architecture construction ages and according to
According to design specification, structure the characteristics of, structure arrangement, construction and the factors such as Seismic Bearing Capacity, carry out construction identification and antidetonation held
Power checking computations are carried, overall merit is carried out to the shock resistance of structure；And using national standard measurement unit, symbol and text, use
Unified technical term, meets existing national regulation standard related request and writes, provides probation report.
The calculation method of the shearing strength of masonry structure component under a kind of different water cut of the present invention, can be to water
The shearing strength of masonry structure component after calamity carries out Fast simulation calculating, has standardized anti-seismic detection after brick masonry structure water impregnates
The method of identification is assessed the damage situations and shear resistant capacity of building after floods, is provided effectively for earthquake relief work
Data supporting, solve the later Hollow Block Masonry Structure Anti-seismic of floods detection mirror technical problem, be vast Testing and appraisal and
Seismic hardening provides powerful support.
