Due to moment resisting connections are made in both directions in steel frames, so beam-to-column web connections are generally as flange connection. The construction and performance under load of web connections are different from flange connections, and there are more difficulties for theory analysis and design. Studies on mechanism of beam-to-column web connections under cyclical load are not only significant to the theoretical research, but also important in practice.

钢结构框架一般纵横两个方向均为框架，梁柱腹板连接非常普遍，构造和受力性能与翼缘连接不同，而且理论分析和设计更为困难，研究钢框架梁柱腹板连接在循环荷载作用下的受力性能和破坏机理并提出抗震设计对策，具有重要的理论意义和重大的工程应用价值。

In fact, beam-to-column web connections are as widespread as flange connections in the steel frames, the principle of strong column weak beam upon the aseismic performance of steel moment resisting frame works as the same in the beam-to-column web connections design.

The unbonded partially prestressed concrete flat-beam frame structure has been used in the practice project in our country, but the aseismatic study of this structure is not perfect at present, study on theory is lagged behind the demand of engineering apply. It has important theoretic meaning and applied value to go deep into the examinational study about the prestressed concrete flat-beam frame structures.This thesis sums up the study of the RC flat-beam frame structure, the PC frame structure, the steel-fiber concrete, the performance of the steel-fiber concrete and its influence to the seismic resistance of the frame.

近年来国内已经开始在实际工程中采用无粘结部分预应力混凝土扁梁框架结构，但是目前对这种结构形式的抗震研究工作还不完善，理论研究已滞后于工程应用的需要，因此深入进行扁梁框架结构的研究，在经济合理的情况下确保该结构的抗震安全性具有重要的理论意义和应用价值。

The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis on propulsive performance was examined using three deflexion modes which are respectively, modified Bose mode, cantilever beam with uniformly distributed load and cantilever beam with non-uniformly distributed load.
