Description

A kind of hollow reinforced concrete shear wall with continuous helical stirrup newel post
Technical field
The utility model relates to a kind of hollow reinforced concrete shear wall with continuous helical stirrup newel post being applicable in highrise building, belongs to technical field of structural engineering.
Background technology
Reinforced concrete shear wall mainly bears the horizontal loading that wind load or geological process cause, its lateral resisting is larger, in the highrise building of highly seismic region, obtains using very widely.But the concrete amount of this solid reinforced concrete wall is large, cost is high, also large from geological process great, that cause, when body of wall is long, depth-width ratio is also very easy to occur shear failure, the ductility of fragility less time poor, because the concrete anti-compression deformability of common stirrup formal constraint is limited, in the time of high axial compression ratio, reinforced concrete wall two ends concrete is easily pressed shortcake, vertical muscle lateral deflection, thereby structure loses supporting capacity.
High for solid reinforced concrete shear wall cost, from the shortcoming great, geological process is large, there is in recent years hollow shear wall, the concrete of solid shear wall body inside is removed a part by hollow shear wall, form vertical hole, thereby reduce construction costs, alleviate dead load, reduce geological process, and meet the requirement of building " energy-conservation, reduction of discharging ".Hollow shear wall is due to the existence of the vertical hole in body of wall middle part, when body of wall is long, depth-width ratio is less time, its failure mode can by the shear failure of fragility change into taking bending failure as main, ductility is better, but its bearing capacity is less than normal, body of wall end concrete easily crushes under high axial compression ratio, is difficult to resist violent earthquake effect.
For the poor shortcoming of the concrete anti-pressure ability in reinforced concrete shear wall end, people arrange steel pipe at reinforced concrete shear wall two ends, have designed concrete-filled steel tube shear wall structure.Because concrete filled steel tube is in three dimension stress state, there is larger resistance to compression deformability, thereby avoid body of wall generation brittle fracture, but concrete-filled steel tube shear wall rigidity and deadweight are larger, can cause larger geological process, and steel pipe cost is higher, in engineering, can consider to replace with the less column with spiral hooping of spacing, because continuous helical stirrup can make core concrete be subject to evenly continuous three dimension stress restraint forces in side direction, the effect of confined concrete lateral deformation is better, and can suppress to a certain extent the lateral deflection of vertical muscle, and cost is lower.
