The utility model is combined to form by built-in spatial mode eccentric supporting steel truss and concrete barrel, and forming process is the process of both additions, but the shock resistance of combination back structure is significantly higher than the addition that steel truss and cylindrical shell work alone.Reason is that combining structure punishment brought into play both advantages separately, has remedied both deficiencies in antidetonation effectively.For concrete barrel, built-in eccentric supporting steel truss has improved its bearing capacity significantly under the condition that does not change its appearance and size, increased its rigidity, has improved its ductility, has increased the building usable floor area, has saved building costs.For the eccentric supporting steel truss of hiding in shear wall, the shaped steel rod member is subjected to the constraint of steel concrete bundle, is difficult for unstable failure takes place, and bearing capacity and ductility all are improved.In addition, common eccentric supporting steel truss after the energy dissipating beam section generation plastic strain, easily causes floor to destroy in antidetonation, is difficult to after the middle shake repair, and the first road anti-vibration defense lines of the present utility model is a shear wall, and energy dissipating beam section is surrendered in big earthquake centre as the combining structure second road anti-vibration defense lines.Compare with combining structures such as the dark support tube body structure of band steel plate, the dark support type steel cylinder of band steel concrete structure, the dark truss concrete combined barrels of built-in center support, the utility model supporting capacity improves, bearing capacity and stiffness degradation are slow, the later stage anti-seismic performance is relatively stable, and the bottom shear sliding rupture alleviates.
Because tubular construction is the core lateral resisting parts of building structure, has improved the shock resistance of shaped steel shear wall, has also just improved the whole shock resistance of shaped steel shear wall structure, when building meets with violent earthquake, can alleviate its earthquake, prevent that it from collapsing.
