  3. While many online resources teach basic web development, few are designed to help novices learn the CSS concepts and design patterns experts use to implement complex visual fea- tures. Professional webpages embed these design patterns and could serve as rich learning materials, but their stylesheets are complex and difficult for novices to understand. This paper presents Ply, a CSS inspection tool that helps novices use their visual intuition to make sense of professional webpages. We introduce a new visual relevance testing technique to identify properties that have visual effects on the page, which Ply uses to hide visually irrelevant code and surface unintuitive relation- ships between properties. In user studies, Ply helped novice developers replicate complex web features 50% faster than those using Chrome Developer Tools, and allowed novices to recognize and explain unfamiliar concepts. These results show that visual inspection tools can support learning from complex professional webpages, even for novice developers.

  4. A lateral force resisting system (LFRS) comprised of one eight-foot-wide Mass Ply Panel (MPP) with Buckling-Restrained Braces (BRBs) was attached to the building frame and tested following a cyclic quasi-static loading protocol up to 4% roof drift ratio. This system was designed to pivot about a pinned base, allowing the wall to rotate with minimal flexural restraint, thereby distributing drift demands more uniformly across the building height and reducing crushing damage at the wall base. Under first-mode loading, the system exhibited stable hysteretic behavior with a nearly uniform story drift profile, while second-mode loading revealed near-linear behavior with high stiffness. Experimental results provide valuable insights into the behavior of mass timber seismic lateral force-resisting systems and can be reused to develop and validate design guidelines for their broader implementation in seismic regions.
