浅谈我国多层混凝土框架结构设计(7)

To the framework structure of the cycle and stiffness calculations often ignored the impact of infilled frame. But the actual situation in the infill wall (brick) in the early stages of the involvement of flexible working capability is greater. So that the structure stiffness is greater than the actual calculation of stiffness, the actual cycle less than the calculated period, calculated too small earthquake. Structural design is unsafe. Held that in order to avoid large errors in the design process should be carried out on computing cycles reduction. General, cycle reduction factor of value: When the wall is filled with masonry, the take 0.6 to 0.7; the light block or masonry wall filled with less time, take 0.7 to 0.8; when filling wall for the lightweight wall boards, the take 0.9; no net framework infilled take 1.0. Can be seen that the stiffness of infilled smaller impact on the framework of the cycle of smaller earthquakes in the ability to absorb the weaker.

III Conclusion

As the frame structure with a large space, flexible layout features, meet the people are constantly seeking to use individual requirements. With the continuous development of society and people's material living standards, the framework structure (residential, public buildings) will be greater development. Design of multi-frame structure , the designer should first determine structural feasibility, potential problems encountered in advance to take measures to resolve, and a careful analysis of all results to determine, accurately be applied to engineering after.

In summary, for me, in the final project (a university building), the specification and according to the actual environment, select the component parameters and design parameters. In addition, we understand more about the structure, construction and other design details. by looking at the specifications, magazines and other literature on the building structure, the design of a concrete understanding of the design for the school well.
