A Material nonlinear finite element analysis for the cast-in-place reinforced concrete hollow slab that occurs from initial loading, cracking, yielding to failing is carried on. The cracking load, ultimate load, the displacement rules and the principal stress distribution rules of the hollow slab under the vertical loads are obtained. A Material nonlinear finite element analysis for the single span hollow flat-plate floor is also carried on. The function of the concealed wide-flat beams is definite by analyzing the principal stress distribution diagram. The calculating results verify the theoretical analysis and give some important conclusions which are great useful to improve the constructing of the new flat-plate floor.

In the part of the vibration experiments and analysis, firstly, used the simple-beam theory to estimate the natural frequency of the beam of the 20-headed computerized embroidery machine.secondly, measured the beam of its low rank natural frequency, the beams horizontal vibrating acceleration amplitude, speed amplitude and the displacement amplitude in different rev and different turn parts. Found that it is sympathetic vibration, which bring on the thread-broken rate rise rapidly. On this base, established the finite element analysis modle of the vibrating beam, and took on hamonic analysis and modal analysis with the mold. The rusult of test and analysis offer the basis for farther improvement of the computerized embroidery machine.
