Description
Technical field
The present invention relates to bridge construction technical fields.
Specifically, being to be related to a kind of installation of brutal or maintenance.
Background technique
In relation to research shows that following 50 years, China probably occur it is especially big, there is destructive earthquake, earthquake meeting
A degree of negative effect is caused to Chinese society and economic development.So we it is necessary to concrete structure bean column node
Performance comprehensively studied, and research and develop new ductile bean column node form, enhance the anti-seismic performance of bean column node, and in reality
It is applied in the engineering of border, reduces casualties and economic loss of the China in earthquake.
So to guarantee more " opposite " safety of column, therefore want " strong column and weak beam ".The mentality of designing of weakening type node is by right
Beam away from certain distance at beam-to-column joint is weakened, and is promoted plastic hinge to occur and extend in beam weak point, is dropped significantly
The low stress concentration phenomenon of node region, avoids node from occurring crack too early, to reach Ductility Design purpose, weak point phase
When in playing the role of fuse.Since plastic hinge occurs and extends in the weak point of beam, so that longer one section of beam is almost
Enter plasticity simultaneously, that is, has been truly realized Ductility Design, has given full play to the plastic property of steel, considerably increased the consumption of structure
It can performance.Replacement and Repair problem after destruction is another research direction of building field.For being connected by screw bolts, with spelling
The replaceable component of fishplate bar can solve the problems, such as to destroy building damage location quick-replaceable, simple to install, construction is simple, consumption
Material is few, reduces expense.It is advantageous to the repairing construction after destruction, reduce operating expenses, improves the efficiency of construction.
Strong column and weak beam is the structuring concept proposed from seismic design of structures angle.It is exactly that column is not broken prior to beam
It is bad, be locality, pillar, which destroys, will jeopardize the safety of total because beam destruction belongs to component damage --- it may be whole
Body collapses, and consequence is serious.
Concrete structure has reasonable utilization of materials, and normability is good, and durability and fire resistance are preferable, and maintenance cost is low, just
Degree is big, is easy to the advantages that gathering materials on the spot, have a wide range of applications field.
