On May 12, 2008, the earthquake that in Sichuan province county of plain of short of Wenshui River produces caused tremendous personnel and belongings loss, also make people right the building that lives daily, and the security that all sorts of public constructions that place of whole society life involves are like office building, school, hospital, bazaar to wait caused more attention.
5 add up to international (many controller of 5 1Werkhart) , engineer makes suggestions in succession when accepting a reporter to interview, propose talk from respect of design, program. The program takes refugee mediumly ground problem5 add up to Tao Tao of general manager of division of international group China to express to the reporter, the city rubble caboodle after seismic indulge in wilful persecution makes a person shocking, although terrified crowd escapes from inside Lou Yu come out, spare hard also suffer fall the harm of made of baked clay slungshot. It is especially in the town below this kind of Chinese high density, the city takes refugee spatial program is attached most importance to especially should. In content of work out of modern town planning, have a main work out project, it is urban take precautions against natural calamities fights calamity to plan, include level of form a complete set of fire control standard, people's air defense, prevent or control flood. But, climb ceaselessly as what urban land price is worth litre, the city decreases hollowly ceaselessly. Accordingly, although there is baronial square in the city, open park, in urgent hour, how does people arrive? In the research content that Beijing control sex planned in detail 1995, also emphasized every street the complete greenbelt that makes sure 3000 square metre are controlled, take refugee mediumly in order to regard a city as take precautions against natural calamities place. From this date from, the system of 3 class greenbelt that living area plans to design the place in the standard to ask, it is the problem of landscape figure not just, more important is the safe space when jeopardy of the put apart in the Lou Yu that must spend in high density. So, living area greenbelt, village greenbelt, form a delegation greenbelt, break ought not to be similar in shape is fine those who be like hairspring is banding afforest, cannot be replaced by building span place more. Tao Tao appeals, china is restricted because of national condition place, building high density community is inevitable trend, but how to hold high density to spend this, the rigor that needs program management department guards a pass, need to develop business more people social conscience, the appeal that also needs social people and supervise. From this, we just can come true we live mediumly in good home and safe. Conduce of structure of wall shears force is aseismaticExpert of high-grade residence design, 5 suit international group vise general manager Yan Tao, 5 add up to Liu Ping of international construction engineer to express to the reporter, at present the target of our country aseismatic design is “ big shock does not fall, shake can be repaired in, small shake is not bad ” . Local shake is cracked degree be more than fortify to crack when spending, although housing arises relatively havoc, also answer guarantee against appears to break down immediately collapse, make personnel has flee for one's life time. From the angle analysis of aseismatic function: Because build and structure of system of build by laying bricks or stones is become by the build by laying bricks or stones such as brick, stone, the join between block is poorer, although installed ferroconcrete construction column, girth to wait,strengthen measure, but when encountering strong shock, in level and vertical stroke to shake alternately below, the join between block is destroyed easily, cause system of build by laying bricks or stones inattentive, vertical stroke is destroyed to component getting power, the building breaks down collapse; Under photograph comparing, frame structure can provide relatively capacious use space, the organization that is helpful for building a function and break up, but its fight side stiffness weaker, appear easily below strong shock action bigger displacement, bring about a structure to arise relatively play havoc with, because this also belongs to aseismatic and adverse structure. The ferroconcrete cuts force wall structure to have the bigger stiffness that fight side, displacement falls in seismic action lesser. The shears that passes aseismatic design force wall structure, below big shock effect, destroy mouth of an opening in a wall of door of meeting bureau be confined to to be in occurrence break, and although wall body craze, each wall limb also but bearing floor, won't happen to break down large-scaly collapse. Frame - structure of wall shears force is proper in frame structure place adds wall shears force, offerring while contented function needs large space, by added shears force wall offers the bigger stiffness that fight side, improve aseismatic performance of the structure. The aseismatic function of all sorts of configuration, the expression that points to a structure to fall in small shake and big shock namely each are not identical. Overall for, the ferroconcrete cuts force wall structure and frame - the aseismatic performance of structure of wall shears force is better, the aseismatic performance of structure of system of build by laying bricks or stones and frame structure is relatively a few poorer.Previous12 Next
