[Grid] rubber bearings for smooth application of the direct beam bottom longitudinal tilt mounted rubber bearings [grid], in order to meet the requirements of the bridge checking the relevant regulations, [grid] bearing rubber bearing compressive stress limits should be taken within the high, short side should take a small plane under the same pressure area, bearing thickness within the limits should be greater. Lateral tilt mounted rubber bearings [grid] bearing from time to consider its impact. Existing structures called to stress to the stress of building seismic grid rubber bearings in the earthquake, serious problems are man-made main bearing components in building structures, the stress applied to the grid of rubber elasticity of concrete load-bearing member bearing, generally through the structure of reinforced bearing components were tensioned using reinforced concrete extrusion resilience to achieve. Based on the load-bearing steel tension members, has relationships with concrete, can be divided into first-tensioned and post-tensioned two categories. From the building structure to stress member, to stress to the development of the structure, have a longer time, the stress applied to the development of components and building structures to stress the advantages of the structure, in many cities in the building, has been relatively wide range of applications. In urban construction and development, promotion and application, and I stress I stress member structure, can indeed play a positive role. However, there is a very important structural dynamics problems require special attention to the so-called structural dynamics architectural problem, that is, when the earthquake broke out, forcing the seismic shock waves generate dynamic response of building structures vibration, seismic shock wave impact structures, to produce internal forces passed in the structure. [Grid] [grid rubber bearing rubber bearing] the role of the designer in the earthquake often only pay attention to the strong charge on the beam and overturning were checking grid isolation rubber bearings, while ignoring the beam deflection hand checking. High beam selection is too small, causing the compression zone of high stress beam section, under normal use, the beam cross-section compression zone to produce nonlinear creep. Deflection increasing over time. Pick the deformation of the beam caused by slab cracks, the crack width as the pick back to the big beam deformation and widen, affecting the normal use of the house. [Grid rubber bearings] According to my observation, this pick to the late development of deformation of the beam, the beam cross section of the upper bearing tension zone vertical cracks often appear wider. By the upper part of the tension zone near the seat of vertical cracks often appear wider. Affected by the shear-bending role holder near vertical cracks extending downward diagonal cracks develop, then the beam is close to destruction, when asked when the wall cantilever beam, the beam deflection caused by excessive body condition beam support beam cracks appeared nearby. Cracks in the beam [grid] at oblique rubber bearings extends along the seam on the more by the more wide. Cantilever beam cross-section is too small for the seismic structure is also very unfavorable. Cantilever vertical seismic effect on the most sensitive. Leung hours relative compression zone section height greater ductility beam decreases, prone brittle failure in the vertical earthquake action, loss bearing capacity. [Grid] continuous girder rubber bearings are designed by a single beam in this case multiple balcony edge beam design. Due to the load side of the beam is generally small, designed to not cause attention, stress analysis conveniently left, designed for the practical application of the beam by a single continuous beam simply supported beam design, resulting in the upper bearing beam at the negative Configuring too little muscle. This will inevitably lead to the vicinity of the beam in the upper bearing tension zone by vertical cracks appear, thereby causing the upper bar plate girder vertical cracks appear.
