国槐抗弯强度、抗弯弹性模量

本数据记录了国槐中抗弯强度、抗弯弹性模量的序号、记录本序号、试样序号、试样宽度、试样高度、试验时含水率、变形、试验时抗弯弹性模量、含水率15%时抗弯弹性模量、破坏荷载、试验时抗弯强度、含水率15%时抗弯强度等记录。木材物理力学的各项测定指标，直接反映此种木材的强度等特性，为木材利用和木结构的规范等提供科学数据。本数据库包括物理力学数据和其试验方法（请参看附件1中华人民共和国国家标准GB1927～1943-91《木材物理力学性质试验方法》，附件2木材物理力学各个项目的定义）。

This dataset contains records related to the bending strength and bending modulus of elasticity of Sophora japonica, including the test record serial number, specimen serial number, specimen width, specimen height, moisture content during test, deformation, bending modulus of elasticity during test, bending modulus of elasticity at 15% moisture content, failure load, bending strength during test, and bending strength at 15% moisture content.

All physical and mechanical test indicators of wood directly reflect the strength and other properties of this wood species, providing scientific data for wood utilization and the formulation of wooden structure codes. This database includes both physical and mechanical test data and the corresponding test methods (please refer to Attachment 1: Chinese National Standard GB1927～1943-91 *Test Methods for Physical and Mechanical Properties of Wood*, and Attachment 2: Definitions of each item in wood physical and mechanical tests).
