An analytical technique for the calculation of the lateral contact forces in buckling-restrained braces (BRBs), proposed by Dehghani and Tremblay (2017), is critically revised and improved. The resulting algorithm is implemented and adopted with the only aim of highlighting what factors are important in the calculation of the lateral thrust in BRBs. Many of these factors seem to have a marginal importance in comparison with the buckled shape of the core, the core steel constitutive law, and the stiffness of the retention profiles. Possible conclusions deriving from this analysis are (i) only the calculation of analytical upper and lower limits for the lateral thrust in BRBs may have a sense, but these limits are always much distant from each other, and (ii) it is worthless trying to adopt over-detailed calculation techniques for this important quantity.

Dehghani和Tremblay（2017）提出了一种用于计算屈曲约束支撑（BRB）中的侧向接触力的分析技术，并对其进行了严格的修订和改进。实施和采用所得算法的唯一目的是强调在BRB的侧向推力计算中哪些因素很重要。与芯子的弯曲形状，芯子的本构定律和保持型材的刚度相比，这些因素中的许多似乎只具有边际重要性。从该分析得出的可能结论是：（i）仅对BRB的侧向推力的分析上限和下限进行计算可能是有意义的，但是这些限制始终彼此相距很远，
