Abstract

This project is a practical project, located in Suqian city of Jiangsu Province, the safety class of the building structure foundation design for two, grade C, seismic fortification intensity is 8 degrees (the first group), the design value of the basic seismic acceleration 0.3g. The length width of the building site is about60.0m * 9.9m, with a total construction area of about , which is six store beam-column frame structure. According to the survey report, the building site category III, near the earthquake, recommended the use of an independent foundation under the column.

Keywords: timber structure； design；wood shear wall； beam–column structure； glulam
