“…The average annual death toll was 112.75, and there was an average of 61.25 building collapse accidents per year 2 , 3 . Furthermore, an average of 1.84 people were killed in each building collapse accident 4 . Frequent building collapse accidents have far-reaching consequences, seriously threatening the lives and property of individuals and bringing about unpredictable direct or indirect economic losses.…”

Rescues from building collapse accidents present a significant challenge for China’s emergency rescue system. However, there are also many risk factors in a training scenario, which have been summarized in this study. A hierarchical indicator system for personnel safety was established, including 12 first-level indicators and 23s-level indicators. Then, an improved Grey-DEMATEL-ISM-MICMAC evaluation model was constructed to evaluate the level of risk. Influencing factor scores were determined according to the responses from the questionnaire survey. The influencing degree, influenced degree, centrality, and causality were identified, and the importance, relevance, and clustering of the various factors were obtained after making quantitative calculations. The results showed that the order of priority for solving the essential issues was safety education (A2), operating standards and proficiency (A10), equipment inspection (A4), equipment warehousing maintenance and records (A21). The solving of safety education was identified to be the most essential priority. The priority control order of direct causes was Scientific design and construction (A5), Potential fixed hazards in the facility (A12), Physical fitness of personnel (A1), Weather influences (A18), and Initiation efficiency of emergency plans (A20), and direct control measures for these five factors could achieve a relatively significant effect.

“…Combined with the advantages of both natural foundation and traditional pile foundation, rigid pile composite foundation (RPCF) has been gradually used in high-rise buildings and also one of ideal foundations for high-rise buildings [1]. At present, study on RPCF is mainly performed through theoretical inference [2], model test [3], in-situ test [4], numerical simulation and so forth [5], thereby acknowledging load transfer mechanism, pile soil load distribution characteristic and law on change of stress ratio of pile to soil thereof. However, due to complicated mechanism of action on RPCF, the load-carrying behavior thereof is still has room for further research.…”

To study the working behavior of a rigid pile composite foundation of high-rise buildings, an in-situ loading test and stress test on piles and soil were carried out. According to the test results, the stress distributions and variations, load transferring characteristics, and stress distributions of piles were analyzed. The results showed that the piles with the formation of non-soil compaction technology can consolidate soil among piles. When the load level was greater than 240 kPa, a better consolidation effect can be obtained. The development negative friction at the top of piles was relevant to the load level. The adjustment effect of cushion on the composite foundation was mainly embodied before the load level reached the characteristic bearing capacity of the composite foundation. Under vertical load, the stress distributions along the internal and external sides of pile shaft were different and the loading plate would bring influence to stress distributions of the pile shaft. The influence range was from the middle to the top of the pile. Based on the test results, it is recommended to reduce the evaluation standard of the bearing capacity determined in the pressing plate test. The results can provide a reference for similar engineering.
