Based on the big data of the gathered experiments, this paper firstly validates the accuracy of the BSCCM for the standard specimen with 45 tests data, and secondly deduces the equivalent transformation formulas for non-standard specimen through the yield line theory and verifies the applicability of the BSCCM for the non-standard specimens with 98 tests data. And on this basis, through data mining and factor analysis, this paper studies the factors that affecting the punching shear strength and deformation and proposes the simplified calculation formulas for engineering practice. At last, this paper fully validates the reasonability and accuracy of the formulas with 432 tests data. Results show that the BSCCM is applied to the calculation of punching shear strength and deformation for both standard and non-standard specimens. The simplified formulas which considered concrete strength, yield strength of steel\/bar, reinforcement ratio, punching span ratio and perimeter thickness ratio of critical section can accurately and rapidly predict the punching shear strength and deformation of the slab-column connection. The conclusion can be available for engineering application and be used as the basis of the performance design of RC flat plate structure.<\/jats:p>","DOI":"10.3233\/jifs-169602","type":"journal-article","created":{"date-parts":[[2018,7,10]],"date-time":"2018-07-10T14:28:55Z","timestamp":1531232935000},"page":"445-459","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Simplified model for estimating the punching load and deformation of RC flat plate based on big data mining"],"prefix":"10.1177","volume":"35","author":[{"given":"Chuanteng","family":"Huang","sequence":"first","affiliation":[{"name":"School of Engineering and Technology, Zunyi Normal College, Xinpu, Zunyi, China"}]},{"given":"Zhijun","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Civil Engineering, Chongqing University, Shazhengjie, Shapingba, Chongqing, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area (Chongqing University), Ministry of Education, Shazhengjie, Shapingba, Chongqing, China"}]}],"member":"179","published-online":{"date-parts":[[2018,7,9]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"Building Code Requirements for Structural Concrete and Commentary","author":"ACI Committee 318","year":"2014","unstructured":"ACI Committee 318, Building Code Requirements for Structural Concrete and Commentary, American Concrete Institute, Farmington Hills, MI, 2014."},{"issue":"8","key":"e_1_3_2_3_2","first-page":"771","article-title":"Punching strengthof flat slabs with and without shear reinforcement","volume":"67","author":"Bartolac M.","year":"2015","unstructured":"BartolacM., Damjanovi\u0107D. and DuvnjakI., Punching strengthof flat slabs with and without shear reinforcement, Gradevinar67 (8) (2015), 771\u2013786.","journal-title":"Gradevinar"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9445(2003)129:9(1173)"},{"key":"e_1_3_2_5_2","volume-title":"Punching of Flat Slabs: The Influence of Slab Thickness and Stud Layout","author":"Birkle G.","year":"2004","unstructured":"BirkleG., Punching of Flat Slabs: The Influence of Slab Thickness and Stud Layout, Department of Civil Engineering, University of Calgary, Calgary, AB, Canada, 2004."},{"key":"e_1_3_2_6_2","volume-title":"Structural use of concrete, Part 1: Code of Practice for Design and Construction","author":"BS 8110-97","year":"1997","unstructured":"BS 8110-97, Structural use of concrete, Part 1: Code of Practice for Design and Construction, British Standards Institution, London, UK, 1997."},{"key":"e_1_3_2_7_2","volume-title":"Design of Concrete Structures","author":"CAN\/CSA-A23.3-04 (R2010)","year":"2010","unstructured":"CAN\/CSA-A23.3-04 (R2010), Design of Concrete Structures, Canadian Standards Association, Rexdale, ON, Canada, 2010."},{"key":"e_1_3_2_8_2","volume-title":"Mode Code for Concrete Structures","author":"CEB-FIP MC 2010","year":"2010","unstructured":"CEB-FIP MC 2010, Mode Code for Concrete Structures, Wilhelm Ernst & Sohn, Berlin, Germany, 2010."},{"issue":"2","key":"e_1_3_2_9_2","first-page":"343","article-title":"Nonlinear, static analysis of flat slab floors with grid model","volume":"111","author":"Coronelli D.","year":"2014","unstructured":"CoronelliD. and CortiG., Nonlinear, static analysis of flat slab floors with grid model, ACI Structural Journal111 (2) (2014), 343\u2013351.","journal-title":"ACI Structural Journal"},{"key":"e_1_3_2_10_2","first-page":"721","article-title":"Static and dynamic response of reinforced concrete slab-column connections","volume":"42","author":"Criswell M.E.","year":"1974","unstructured":"CriswellM.E., Static and dynamic response of reinforced concrete slab-column connections, ACI Special Publication42 (1974), 721\u2013746.","journal-title":"ACI Special Publication"},{"key":"e_1_3_2_11_2","volume-title":"Plain, Reinforced and Prestressed Concrete Structures-Part 1: Design and Construction","author":"DIN 1045-1","year":"2008","unstructured":"DIN 1045-1, Plain, Reinforced and Prestressed Concrete Structures-Part 1: Design and Construction, Normenausschuss Bauwesen (NABau) im DIN Deutsches Institut f\u00fcr Normung e.
