[Grid] rubber bearing brick structure constructed house doubles as a load-bearing column by column in the brick structure, the structure will not only improve the pit wall shear capacity, and structural columns and beams imprison linked together to form a pair of masonry Ball bearing seismic grid constraints relic preservation, which carry restrictions wall cracks, maintaining the vertical bearing capacity, improve the seismic performance of the structure plays an important role. In the current design of the complete specification grid damping ball bearing, structural columns are often used as a load-bearing column, this approach will lead to the following questions. 2.1 is used as a load-bearing column structural columns, making structural columns in advance by force, which will not only reduce the structural columns of thorough and Rachel and constraints for, and once when an earthquake structural role in the structural column position inevitable stress concentration, first destruction. Such structural columns only not achieve its proper role, but has become a weak housing construction site. [Grid] rubber bearing structural columns are generally rooted in the ground ring beam, there is no separate foundation, structural column after column to use doubles as a load-bearing column bottom base of the anti-punching, bending department and local bearing strength can not meet the requirements of necessity . Once the bottom of the column base is die-cut or partial pressure cracks occur. In this paper, load-bearing pillars proposal shall be under the load-bearing beam column design. If the beams are relatively small load and span, structural columns can also be arranged in the lower beam, but you must press does not consider the role of structural columns to checking local compression and flexural strength under the wall. Experience count to meet before structural columns arranged in the beam. For shun direct beam bottom longitudinal tilt mounted rubber bearings [grid], in order to meet the requirements of the bridge checking compliance-related, rubber bearings [grid] stress within the limits should take high pressure area under the same plane short side should take a small, rubber bearings [grid] thickness within the limits should be greater. Lateral tilt installation of seat time to consider its impact. [Grid] rubber bearing modern seismic design ideas modern seismic design ideas and relationships in the current theory of the formation of the earthquake, the main contents are: 1. a reasonable choice to determine the structure of the yield earthquake standards. Usually the first with a statistically significant peak ground acceleration value as a symbol of the strength of the earthquake area (ie the earthquake) finished grid elastic support of the old brand, and then to a different R (seismic force reduction factor) obtained with different design ground motion acceleration (ie, small earthquakes) to design the structure strength, rubber bearings [grid] in order to determine the yield level of the structure. 2. The development of effective measures to seismic design of structures does have adopted corresponding R ductility capacity. Adjustment measures which include internal forces (strong column weak beam, strong shear weak bending) and seismic design. Modern seismic design philosophy is based on the study of non-elastic properties of the structure set up, its core is the relationship, the relationship is mainly refers to the different rules and hysteresis characteristics of the ground motion, vibration periods yield level and structure as well as the largest non-elastic force the relationship between reaction. Where R is the inelastic response of seismic force reduction factor, referred to as seismic force reduction factor; rather than the maximum inelastic displacement and yield displacements, called displacement ductility factor; T was obtained by the elastic stiffness of the structure of natural cycles. [Grid] rubber bearings 1960s, researchers in the hysteresis curve for the ideal elastic-plastic and elastic stiffness is always the same premise, through different periods, different yield levels of inelastic SDOF systems do dynamic analysis, has been under the relevant laws of the maximum displacement of inelastic response: T is greater than 1.0 seconds for a system suitable for "equal displacement rule" that is non-elastic response of maximum displacement under total equals the maximum displacement of the elastic response under the same ground motion input.
