It looks like you're looking for a quick revision guide on Limit State Method (LSM) and Working Stress Method (WSM) for RRB-JE CBT-2 (Civil Engineering), specifically for Reinforced Cement Concrete (RCC). Here's a brief overview to help you:

Introduction to LSM & WSM
1. Working Stress Method (WSM)
Concept: Based on elastic theory; assumes material remains within elastic limit.
Factor of Safety (FoS): High, leading to conservative designs.
Serviceability: Ensured but can lead to uneconomical sections.
Assumptions:
Linear stress-strain relationship.
Load and resistance factors not explicitly considered.
Disadvantages: Does not consider material behavior beyond the elastic limit.
2. Limit State Method (LSM)
Concept: Ensures both safety and serviceability under ultimate loads.
Ultimate Limit State (ULS): Ensures strength against collapse.
Serviceability Limit State (SLS): Ensures deflection, cracking, and durability control.
Advantages:
More economical than WSM.
Provides better utilization of material strength.
Used in IS 456:2000 (Indian Standard for RCC design).
RCC Quick Revision
Basic Materials:

Cement, Aggregates, Water, Admixtures, Reinforcement Steel.
Strength parameters: Compressive (concrete), Tensile (steel).
Design Philosophies:

WSM: Based on elastic theory.
LSM: Based on safety & serviceability.
Ultimate Load Method (ULM): Earlier method, now obsolete.
Flexural Members (Beams & Slabs):

Neutral Axis (NA) Concept: Division between compression and tension zones.
Balanced, Under-Reinforced, Over-Reinforced Sections.
Shear & Bond:

Shear Reinforcement: Stirrups, Bent-up bars.
Development Length (Ld): Ensures bond strength.
Columns & Foundations:

Short vs. Long Columns: Slenderness ratio effect.
Footing Design: Based on soil-bearing capacity.
Deflection & Cracking:

IS 456 Limits for allowable deflection and crack width.#examexpress
