Changzhou Tianning Pagoda with steel structure 2.
Thirdly, they must be high, so that they can look farther.
In addition, the construction law of the people’s Republic of China has provisions advocating the use of advanced technology, advanced equipment, advanced technology, new building materials and modern management methods《 The law of the people’s Republic of China on earthquake prevention and disaster reduction contains provisions that the State encourages and supports the research, development and popularization of new technologies, new processes and new materials that meet the requirements for seismic fortification and are economical and practical.
Figure 1.
The steel structure of the pagoda was capped at the end of 2003.
It is found that the groundwater level changes with the water level of Wenhu Lake next to Wenfeng tower, resulting in uneven settlement of Wenfeng tower foundation; The damage of the ancient tower caused by the earthquake in the 1920s is an important reason for the inclination of Wenfeng tower.
A: 1.
With such accuracy, Tianning pagoda won the first award: the gold award issued by the national steel structure association in 2004.
Steel structure of Hangzhou xinleifeng tower Q: is there a saying of “ancient law” in this era? Especially the so-called “ancient method” to build a 100 meter high tower? Does it work? A: the so-called “ancient law” is obviously suspected of violating the national laws and regulations on earthquake prevention and earthquake resistance.
Second, due to the underdevelopment of ancient science and technology, scientific, accurate and detailed geological exploration could not be carried out, and the geological structure of many tower foundations was unstable, resulting in the inclination of the tower body; Third, earthquakes and other geological disasters caused the ancient pagoda to tilt or even collapse.
On March 11, 2016, xinhuanet.com issued a document entitled “the world’s tallest ancient brick tower is inclined, and experts say that ‘ten towers and nine slopes’ are not exaggerated”, which was specially discussed in this report; Architect Zhao Xiaojie also wrote in his paper on the fall of Leifeng Tower – the durability of Chinese Tower: durability is a problem that Chinese tower has not been solved.
China is an earthquake prone country.
At present, the highest Pagoda in the world is Changzhou Tianning Pagoda with 13 floors, a total height of 153.79 meters and a clear height of 108 meters.
It can also be used as an example of an 80 meter high tower.
The construction of buildings and structures must strictly comply with relevant national laws and regulations.
Comprehensive maintenance was carried out from 1988 to 2003.
Figure 2.
First, the rescue and reinforcement of each layer of the tower was carried out, and then the collapsed northeast corner and the tower brake were restored and reinforced..
Earthquakes often bring devastating disasters to the tower, so earthquake prevention and earthquake resistance are very important.
Therefore, the design of ancient Chinese towers must be hollow, with stairs, so that people can climb up.
It has a total construction area of 27000 square meters and 6500 tons of steel to support the tower skeleton.
Tianning pagoda adopts the style of ancient pagodas in the Tang and Song dynasties in terms of shape and body decoration: octagonal cornices, dignified shape, grand momentum, quaint and solemn.
Moreover, there is no content in the search for the word “ancient law” on the official website of the Ministry of housing and urban rural development of the people’s Republic of China; Search the word “earthquake resistance” and find 1729 relevant results; Search the word “earthquake prevention” and find 239 relevant results.
Figure 3.
At the end of 2002, the famous landscape Leifeng Tower along the West Lake in Hangzhou was rebuilt.
Based on the idea of repairing the old as the old, but also ensuring the stability and safety of the new tower, and meeting the seismic, fire and other safety measures required by national laws and regulations, the new Leifeng Tower adopts an all steel frame structure, with tiles, ridges, bucket arches, columns and other copper components, and four sightseeing elevators.
Tianning pagoda was built in April 2002 and opened on May 1, 2008.
The tower is not only a part of the landscape skyline, but also a place to climb high and look far.
The rebuilt Leifeng Tower is 71 meters high, and the internal space fully reflects the modern functional requirements.
The 83.7-meter-high Kaiyuan Temple Tower in Dingzhou, Hebei, built in the Song Dynasty, with brick and wood structure, collapsed in the northeast corner of the tower in the tenth year of Guangxu of the Qing Dynasty (1884).
This is not a “ancient method” to make cup bowl clothes jewelry and other private small objects.
Secondly, there must be an ambulatory for people to stop and look far.
It can be seen that the Ministry of housing and urban rural development is completely using relevant laws and regulations to ensure the legality, quality, safety and other elements of construction, does not involve the so-called “ancient method” masonry, and has not formulated corresponding laws and regulations for “ancient method” masonry.
From the perspective of durability, Chinese tower is a failed architectural type.
Through the unique “tower in the tower” structure, the Leifeng Tower site is protected to the greatest extent and the original style of Leifeng Tower is followed.
《 Article 35 of Chapter IV of the law of the people’s Republic of China on earthquake prevention and disaster reduction stipulates that new construction, expansion and reconstruction projects shall meet the requirements for seismic fortification.
Many famous domestic experts and scholars were invited to demonstrate this renovation.
After precise measurement, the verticality error between the tower tip and the bottom is less than 1 cm.
After several earthquakes, fires and lightning strikes, it is now 71 meters high.
If you want to build a 100m high tower with the so-called “ancient method”, please be vigilant and have the right to report according to law《 The law of the people’s Republic of China on earthquake prevention and disaster reduction stipulates that any unit or individual has the right to report illegal acts in earthquake prevention and disaster reduction activities《 The regulations on the administration of earthquake resistance of construction projects stipulates that any unit or individual has the right to report illegal acts in violation of these regulations.
Many experts and scholars say that China’s ancient pagodas are “ten pagodas and nine slopes”.
Wenfeng temple in Fenyang, Shanxi, has tilted 1.82M to the East in 2016 2.
Q: are antique buildings outside the law of the current national laws and regulations on construction projects? A: the definition of antique buildings in the specifications (Draft for comments) issued by the Ministry of housing and urban rural development makes it clear that antique buildings are built with modern structure, materials and technology, and only the appearance imitates the style of ancient buildings.
Q: how about the tilt and collapse of many ancient pagodas? Please give an example.
The mandatory provisions that must be strictly implemented in the national standard code for seismic design of buildings (gb50011-2010) stipulate that buildings in areas with seismic fortification intensity of 6 and above must be subject to seismic design; The height of multi-storey masonry houses in areas with seismic fortification intensity of 6 shall not exceed 21 meters and the number of floors shall not exceed 7.
Based on various studies, the main reasons are as follows: first, the ancients had structural defects in the design of ancient pagodas, which is the internal reason for the inclination of pagodas.
Therefore, the construction of antique buildings must comply with the national laws and regulations on construction projects, which is not an extrajudicial place.

At the same time, it also buried the curse of the easy collapse of the Chinese tower.
Among the existing ancient pagodas in China, more than 80 meters is the largest height.
A: the damage of three ancient pagodas with an original height of more than 80m is shown briefly.
In the spring of 2016, Xinhuanet and other media reported that the Wenfeng tower in Fenyang, Shanxi, which was built in the late Ming and early Qing Dynasties, with a green brick structure and a height of 84.93m, was gradually inclined, and the latest measurement found that it had tilted 1.82M to the East.
Can the so-called “ancient method” be used to build a 100 meter high tower in this era? Does it work? Q: what is the definition of antique buildings by relevant state departments? Answer: in the code for calculation of quantities of antique buildings (Draft for comments) issued by the Ministry of housing and urban rural development on October 18, 2019, 2 terms 2.0.3 antique buildings: antique buildings refer to buildings and structures built with modern structures, materials and technologies in imitation of the style of ancient buildings.
Q: what antique towers are built with modern structure, materials and technology? Please give some examples.
There are 4 Chongwen pagodas in Jingyang, Shaanxi, Wenfeng pagodas in Fenyang, Shanxi, Kaiyuan Temple pagodas in Dingzhou, Hebei, and Zhongjing Daming pagodas in Chifeng, Inner Mongolia with an overall height of more than 80m, two of which have problems of inclination or collapse; In addition, the Taiping Xingguo temple tower in Yuncheng, Shanxi Province, was originally 86 meters high.
