The influence of friction energy dissipating bracing stiffness on suppressive effectiveness of structure vibration;

First,the solution to the bracing stiffness optimization problem of braced frame structure on rigid foundation is studied with the structure soil interaction taken into consideration.

Analysis and design method for transfer truss with diagonal brace that was widely used in Beijing MOMA was studied.

In this paper, by means of shaking table test study on 15-floors reinforced concrete frame model with hetero-columns and diagonal braces, the natural vibration property, history process and frequency-spectrum feature of earthquake action are analysed.

The article analyses the error of compound internal forces of diagonal brace in full live loading method, and amends the compound factor of internal forces under vertical loads.

The complex damping properties are analyzed for the combined damping elements of brace and viscous dampers or viscoelastic dampers in series.

It is introduced how to estimate the lateral displacement of the multiple floor and single span braced frames.

The application of triangle homolateral supporting bar inclined shore in prevent waterwave concret wall;

Effect of diagonal bracings in the sidewall of plastic greenhouse frames on longitudinal stiffness;

In a foundation pit in soft soil area, gravity retaining wall with diagonal bracing is used as well as those without bracing.

When the engineering piles and support piles are put into full practice,measures such as well point unwatering,unloading and punctual diagonal bracing are used according to the different excavation depths in the foundation pit so that construction time has been shortened,safe construction of the underground garage realized and the safety of the surrounding buildings secured.
