In 1997, the results of composite slab beams were successfully applied to the deck system of long-span suspension bridges, such as Shenzhen rainbow bridge.

The research results were successfully applied to the centralized control building of the phase V project of Taiyuan No.

Nie Jianguo began to carry out experimental research on steel-concrete composite slab composite floor in 1988, including the tests of simply supported concrete composite slab and continuous concrete composite slab, and the tests of simply supported steel-concrete composite slab composite beam and continuous concrete composite slab composite beam.

No “beard reinforcement” and “truss reinforcement” at the plate end.

Since 1993, Nie Jianguo has conducted a series of in-depth studies on steel-concrete composite slab bridges.

He found that the shear reinforcement (now truss reinforcement) on the upper surface of precast concrete slab under static load is redundant, which not only increases the cost, but also inconvenient for construction.

Since 2015, Nie Jianguo began to pay attention to the cast structure, led the team to propose a new simplified construction technology of canceling the beard reinforcement at the end of the precast slab, carried out the experimental research on canceling the “truss reinforcement” on the upper surface of the precast slab again, and suggested to cancel the truss reinforcement in the building floor mainly bearing static load.

Subsequently, this achievement was rapidly popularized in China.

The research results of steel-concrete composite slab beam were first applied to the bridge project – Beijing Guomao Bridge in 1993.

Its achievements have been successfully applied to Guangzhou Baiyun station of high-speed railway hub, comprehensive service center of Shenzhen Pingshan high tech Zone, phase II of xiong’an business service center and dozens of bridge projects.

Then, it was popularized and applied in the large-span conjoined structure of Zhuhai science and Technology Park (the span of laminated plate composite beam reached 35m) and other projects built in 1999.

The lower traffic was not interrupted during the bridge repair, and the construction period was shortened by more than 50%.

Breaking through the “neck” technology depends on innovation.

In recent years, a series of new technologies and methods of precast concrete structure developed by him have important theoretical significance and practical value for promoting the healthy and sustainable development of precast structure and building industrialization.

This achievement can not only greatly simplify the construction and improve the efficiency, but also have remarkable economic benefits.

1 thermal power plant, a national key project at that time for the first time, and achieved the effects of light large-span, prefabrication and assembly and rapid construction, with remarkable technical, economic and social benefits.

Outstanding contribution in 1988, Nie Jianguo’s achievements on concrete composite slab and steel-concrete composite beam laid the main foundation and provided important support for the development of steel-concrete composite slab composite structure in China.

Nie Jianguo said that innovation, especially original innovation, is very important.

The application effect was highly praised by peers.

As a civil engineering science and technology worker, we should have professional conscience, social responsibility and responsibility spirit to the country and society, constantly solve practical engineering problems and promote the progress of the industry.

To engage in civil engineering is to build a beautiful China.

There was no scaffold and no formwork construction.

In addition, in the fields of connection of precast concrete column end and lateral connection of precast wall, he has developed a series of new technologies with simplified structure, safety and reliability, and has been authorized with a number of invention patents.

According to the report of relevant departments, more than 400 steel-concrete composite beam bridges have been built in Beijing alone.
