Collapse
analysis of neighboring buildings under long-period seismic
excitation
In the conventional design of a building, only static analysis in the horizontal
and uniaxial directions is commonly carried out, in order to minimize calculation
costs. This approach can ensure the structural strength of the building,
if there is sufficient strength to support the load in the vertical direction.
For a similar reason, the mass system model replaces the building layer
in dynamic analysis, and the complicated dynamic behavior of the structure
at the member level becomes difficult to be examined sufficiently. Therefore,
the development of a more precise and more efficient dynamic analysis code
is strongly desired.
Recently, significant advances in the field of computers have been eliminating
the calculation cost restrictions, and various dynamic analysis codes are
being developed. Among those codes, there are some codes applicable to
dynamic collapse problems which contain strong nonlinearities and discontinuities,
such as the Distinct Element Method (DEM) or the Discontinuous Deformation
Analysis (DDA). These codes have been applied to demolition analyses and
seismic collapse analyses. However, the above-mentioned discrete numerical
methods are computationally intensive and need detailed modeling. Therefore,
they are suitable only for detailed analyses of either two-dimensional
or small three-dimensional models.
On the other hand, the Finite Element Method (FEM), which is based on continuum
material equations, has been successfully applied to a wide range of engineering
problems including structural analyses of large-scale structures. However,
the FEM is generally limited to analyses of relatively small displacements
and it needs complicated modifications to simulate fracture occurring in
structural members or joints. The main objective of this study is to develop
a finite element code, which can simulate dynamic behaviors with such strong
nonlinearities and discontinuities and is efficiently applicable to seismic
collapse analyses of framed structures.
Toi and Isobe developed the Adaptively Shifted Integration (ASI) technique
for the linear Timoshenko beam and the Bernoulli-Euler beam elements, which
can be easily implemented into the existing finite element codes. In this
technique, the numerical integration point is shifted immediately after
the occurrence of a fully plastic section in the element so that a plastic
hinge is formed exactly at that section. As a result, the ASI technique
gives more precise elasto-plastic solutions than the conventional schemes,
and has become able to simulate dynamic behaviors with strong nonlinearities
by using only a small number of elements for a member. Structurally discontinuous
problems have also become easily handled, by shifting the numerical integration
point of the linear Timoshenko beam element to an appropriate position,
and by releasing the resultant forces in the element simultaneously However,
when the number of elements per member is very small, it still lacks accuracy
in the elastic range compared to the converged solution, due to the low-order
displacement function of the linear Timoshenko beam element.
To improve the accuracy in elastic range, Isobe and Lynn modified the ASI
technique into an ASI-Gauss technique. The accuracy in elastic range is
improved by placing the numerical integration points of the two consecutive
elements forming an elastically deformed member in such a way that stresses
and strains are evaluated at the Gaussian integration points of the two-element
member, where the accuracy of bending deformation is mathematically guaranteed
for two-point integration. The rest of the shiftings are done according
to the flow of the ASI technique.
In this study, the ASI-Gauss technique is implemented into the finite element
code in order to develop a more precise and less-calculation-time-consuming
seismic collapse analytical tool. The purpose of this study is to verify
the validity of the ASI-Gauss technique in seismic collapse analysis and
to construct a highly efficient structural design tool for framed structures.
An analysis involving member fracture and contact is performed on a large-scale
framed structure to show the practicability of the scheme.
Collapse
analysis of neighboring buildings under long-period seismic
excitation
Collision of neighboring buildings under long-period seismic excitation is also a big issue. We focused on a specific apartment house with three same type 14-story buildings consecutively built with very narrow gaps of 10 cm in between, where two out of the three totally collapsed in the 1985 Mexican Earthquake. EW, NS and UD components of SCT seismic wave are subjected to the fixed points on the ground floor. The dead load for each floor is assumed to be 4.0 kN/m2. The time increment is set to 1 ms, and the calculation is done for a total of 183,501 steps. The analysis takes approximately 4 days with a personal computer (CPU: 2.93 GHz Xeon).
In this case, we set the natural period of the north building model to be 25% longer than the others. The difference of natural periods was actually observed in the same type buildings, caused by the damage that remained after past earthquakes. According to the numerical results, the collision of buildings may be generated by the difference of natural periods between neighboring buildings. The north building with a longer natural period first collides with the middle, consequently changing the natural period of the middle, which ends up generating other collisions between the south and the middle. The middle building first initiates collapse due to continuous collisions given from both sides, around 73 s from the start of seismic activity. Although the north building collapses a few seconds after the middle, the south building withstands the collisions and resists collapse.
