Collapse of Prefabricated Panel Buildings in Shenyang

There is no clearly recorded case of the overall collapse of prefabricated panel buildings in Shenyang, but there have been building safety accidents related to prefabricated components. Here are specific incidents and analyses:

I. Balcony Collapse Incident (March 18, 2025) A balcony collapse occurred in the family building of the old construction company in Xinmin City. The building involved is an old residential area with a 32-year history. The homeowner on the fourth floor illegally renovated the balcony, and the vibration from the renovation work by the third-floor residents led to the overall collapse of the fourth-floor balcony. The wall below the collapsed part completely detached, resulting in one pedestrian being seriously injured and two others being slightly injured. It should be noted that the collapsed part in this incident was the balcony, which is a local structural damage to the building and not an overall collapse of the prefabricated panels. Residents confirmed that the fallen part was the balcony, revealing a gray wall, which had nothing to do with the prefabricated panels.

II. Wall Detachment Accident (March 4, 2012) An exterior wall decorative platform (prefabricated component) fall incident occurred in the Shen Tie Xuesong Xincheng Community in Sujiatun District. The exterior wall decorative platform (prefabricated component) on the east side of Building 5 on Xuesong Road, between the 17th and 18th floors, fell from a height of about 60 meters, forming a 4-meter-long inclined prefabricated panel hanging in mid-air. A black car was damaged, but no casualties occurred. After the building was occupied in 2009, bulging appeared on the building the following year. The developer only made simple repairs, and there were many repair marks on the exterior facade. This incident shows that prefabricated components (such as exterior wall decorative platforms) may have a risk of detachment due to poor construction quality or improper maintenance, but it is a local component failure, not an overall building collapse.

III. Resident Appeal Incident (2025) Residents of Building 1* on Shenliao Road North 1st Lane reported building subsidence and foundation fragmentation. The building is an 80-year-old light-weight pink-brick prefabricated panel structure, which has affected normal life. The official response stated that the address does not belong to a dangerous building, and if residents believe the building is dangerous, they need to bear the cost of identification themselves. This incident suggests that old prefabricated panel buildings may have structural safety hazards, but no actual collapse has occurred. Professional identification is required to confirm the risks.

Summary: Among the incidents involving prefabricated panel buildings in Shenyang, no overall collapse cases have been found, but there have been local structural damage incidents such as balcony collapses and prefabricated component falls. Old prefabricated panel buildings need to focus on structural safety, undergo regular maintenance and inspections, and avoid risk factors such as illegal renovations or construction vibrations.
