Slip Phenomenon

In ancient China timber building earthquake damage records, often about "column small feet slip", scholars in ancient timber buildings for the seismic performance study, also thought that "column small feet slip" is one of the reasons for the ancient building in the earthquake Could be survived. This article through to column small feet slip phenomenon, to lead to column small feet slip condition were analyzed, and "column small feet slip" seismic effect evaluation, is to the ancient timber aseismic performance research achievements added.

Code Provisions

The Whittier Narrows earthquake has been the first earthquake to affect a significant number and many of the same elevator systems that now conform to the more stringent code provisions introduced after the 1971 San Fernando earthquake. While the relative damage potential of the two earthquakes is not now known, much less manchine room and rope damage was observed. The incidence of counterweights coming out of their guide rails was much less than it was from the San Fernando earthquake but still quite common. The performance and operation of elevator earthquake protection devices, seismic switches and counterweight derail detection devices, did not fully meet expectations but they did significantly reduce damage and the potential for injury. There was some inconsistency in the triggering of seismic switches. The seismic performance of elevators suggest that several changes to codes should be considered including a requirement to report earthquake damage and prevent seismic devices from being reset by unauthorized personnel.

Unreinforced stone masonry pagodas have great cultural value and should be detailed investigation its mechanical properties. These buildings were not designed to resist earthquakes in ancient China, at least not in the way of current methods. The objectives of this research were to understand the dynamic behavior of unreinforced stone masonry pagoda and its seismic performance. To accomplish these, a 1/12 scale model of China Dinosaurs Pagoda was constructed and tested on shaking table. The octangle model height is 3.96m, with aspect ratio of height to width is 2.93, both parameters exceed the stipulated limit of Code for Seismic Design of Building. The model built with the stones and motars similar to the prototype materials and the arrangements. Its dynamic behavior and seismic performance were tested on the shaking table towards the free vibration and three earthquake waves. The experimental program adopted in the research is explained in this paper.

In recent years,frequent fires and earthquake make the buildings damage badly,and it causes huge economic loss. Concrete filled double skin steel tubular (Hereinafter referred to as CFDST) as a new member of structure,its mechanical properties are similar to concrete filled steel tubular,at the same time has better fire performance and seismic capacity. Based on this background,the paper expounds study the mechanical performance of CFDST is very important,the hysteretic behavior is the main mechanical indexes of the seismic performance of CFDST after exposure to fire. The study of it will fill the new component in the blank of seismic performance research.

The paper introduces a method for connecting fabricated shear wall with beam in a plane by sleeve, and uses the finite element software to analyze and compare the seismic performance of precast wall beams node and cast wall beam node. It concluded:Seismic performance of prefabricated wall beam node and cast wall beam node are basically the same , while the prefabricated wall beam node has higher strength, which indicates that the connection of precast specimen is reliable. However, before putting it into practical, application, further study on it is still necessary.
