A　rectangular　laminar　shear　rectangular　soil　box　was　designed　and　fabricated　that　consisted　of　multilayer　steel　frames　to　minimize　the　influence　of　the　boundary　effect　of　soil　boxes　used　for　the　soil-structure　shaking-table　tests.　Omnidirectional　rolling　bearings　were　placed　between　the　vertical　adjacent　frames　of　the　soil　box,　allowing　the　frame　to　rotate　in　any　direction　out　of　plane.　The　dynamic　characteristics　of　the　laminar　shear　soil　box　are　analyzed　based　on　computer　modeling　and　the　shaking　table＇s　movement.　Results　showed　that　the　natural　frequency　and　damping　ratio　of　the　laminar　shear　soil　box　were　considerably　different　from　those　of　the　soil　sample.　The　acceleration　of　time　history　and　the　frequency　spectrum　of　each　measuring　point　at　the　same　depth　of　the　soil　sample　were　highly　consistent,　and　the　boundary　effect　index　associated　with　each　measuring　point　was　low.　The　influence　of　the　boundary　effect　can　be　effectively　eliminated　using　the　laminar　shear　soil　box;　therefore,　it　can　be　used　in　the　soil-structure　shaking-table　tests.　©　2021　American　Society　of　Civil　Engineers.
