Description
Technical field
The invention belongs to structural engineering fields, and in particular to a kind of anti-collapse tube structure of damping.
Technical background
Stair vertical uniform load q is only considered in traditional structure, Aseismic Design is not carried out to it, is caused in each violent earthquake, greatly
Part should be destroyed seriously as the stair of escape route, cause huge casualties.Moreover, under geological process,
Only consider that stair may not be able to guarantee the intact of staircase with main structure disengagement, under stronger geological process, stair
Between whole or part may occur collapse.Meanwhile traditional structure staircase is weaker, structural corner stress under geological process
It concentrates, is not suitable for the setting of escape route staircase in corner, this defect is that architectural design causes obstruction.
Summary of the invention
The present invention proposes a kind of anti-collapse tube structure of novel damping, and can dissipate seismic energy under earthquake, is shaking greatly
